Living with cat allergies AND cats

Do you suffer wheezing, sneezing, watery eyes and itchy eyes and arms around your cat? For me, these allergy symptoms are a small price to pay for the company of my cats – although some mornings when I wake with a heavy head and red eyes I wonder!

Cat allergies are not caused by cat hair as most of us assume. They are caused by a protein found in cat saliva, urine and skin cells, or dander. The immune systems of people with allergies mistake this harmless protein for a dangerous invader like a virus or bacteria and mount a full scale attack on it.

Here are some tips for minimising our allergy symptoms without giving up our cats.

• Made your bedroom a cat free zone
•  Reduce the load of cat allergens in your bedroom by washing or replacing bedding, curtains and pillows. Then cover pillows and mattress with allergen-proof covers.
• Open windows wide at least once a day to air the house and dilute the allergen load
•  Send your cat outside, preferably into an outdoor run, to disperse some of the dander
•  Eliminate allergen traps such as carpet, rugs and upholstered furniture as you can. Carpet accumulates up to 100 times more allergens than vinyl or wood flooring. If you can’t take it up steam clean it regularly and vacuum with a high efficiency particulate arresting (HEPA) filter or us and allergen-proof vacuum cleaner bag.
• Brush your cat outside and/or in an outside enclosure to minimise contamination of your home with dander
• Wipe the dander away with a moist cloth or wipe to remove saliva and dander.
• Spray the house with anti-allergen sprays
• Use a low dust cat litter and ask non-allergic family members to clean the litter box frequently
• Take the antihistamines, decongestants, eye drops and aerosol inhalers your doctor recommends. Antioxidants such as Vitamins C and E also have anti-allergen effects.

 Don't let allergies come between you and your feline friend.

Snotty cats

Snotty-nosed and snuffly cats are difficult to live with. Their owners put up with sneezesand snot all over the house, as well as snuffles and grumbles all day and half the night.

The causes of sinusitis and rhinosinusitis are also difficult for vets to diagnose accurately and even more difficult to treat effectively.

Inflammation and infection spread rapidly from cats’ throats to adjacent structures, such as the middle ear, frontal sinuses, nose and tympanic bullae. These cavities are difficult to reach with medical or surgical treatments.

Felinemucus is also thicker than human mucus and medication has a hard time penetrating the mucus to get to the offending microbes.

Feline Herpesvirus is the most common initiating cause of chronic rhinitis and rhinosinusitis. It causes chronic airway inflammation and swelling, destroys the normal lining of the nasal cavity and upsets the normal mucus layers. The nasal cavity cannot remove foreign particles or the abnormal mucus and the sinuses become blocked. Bacteria leap in and set up infections making the situation even worse.

Drugs to reduce the mucus and the swelling in the sinuses help a bit. We treat the bacterial infection with antibiotics but are still left with Herpesvirus and all the damage it does. Herpesvirus sinusitis soon flares up into full blown bacterial sinusitis again. Some cats respond well to antiviral drugs but others keep getting intermittent sinusitis.

Nastier causes of similar signs are Cryptococcosis, a fungal disease, and cancer,commonly lymphoma, adenocarcinoma and squamous cell carcinoma. These are difficult to distinguish on X-ray but CT or MRI are very helpful, if they are available. A biopsy clears up any doubts. A blood test is available for Cryptococcosis.

Bad teethand infected tooth roots sometimes make cats snuffly. A dental inspection and X-ray under general anaesthetic allow targeted and successful treatment.

Occasionally a cat breathes in a grass seed or other foreign body. Usually nasal discharge is from one side only and there is some bleeding.   

Is an older cat for you?

Just came across this great article on the advantages of adopting an older cat. Sometimes kittens aren't all they're cracked up to be...
Cute or wise?

Paracetomol poison to cats

Don't be tempted to medicate your off-colour cat with paracetamol this holiday season. Paracetamol at any dose is deadly to cats.
Soon after ingesting it cats' red blood cells lose the ability to carry oxygen. The cats' gums turn brown, they drool and they become weak and wobbly.
If they survive the first 12-24 hours the liver starts to close down, too. They go off their food, their face, lips and paws swell, their gums and eyes go yellow and their belly swells.
Most cats who ingest paracetamol die unless treated within the first couple of hours.
Aspirin is equally dangerous but more subtle in its effects. Aspirin damages cats' kidneys and irritates their stomachs.
Very few pain medications are safe for cats. Only give medications prescribed by your vet for your particular puss.

Tick paralysis

Already this spring we have treated a cat back from the beach with tick paralysis.

Reports from the coast say that the ticks are the worst seen in many years.

Treat your cat for ticks before you leave for the coast.

Frontline spray is the only safe tickicide for cats. Apply 2 days before leaving for the coast and then fortnightly while down there.
Advantix and Permethrin are extremely toxic to cats. A cat brushing up against or grooming a treated dog can die of permethrin poisoning.
Supplement the tickicide application with close daily inspection of your cat. Feel inside the ears, under the arms, around the tail and in all the crevices and skin folds. Ticks love to hide in long hair. Remove any ticks you find immediately.
If your cat is weak in the legs or drooling contact a vet immediately.

A must see!!!

Another reason to give up smoking

Cats who live with smokers have a higher risk of developing cancer. 

The risk of lymphoma, the most common cancer in cats, is tripled in cats from smoking households. Squamous cell carcinomas of the mouth are also more prevalent in cats exposed to tobacco smoke.

Scientists from all over the world have detected nicotine metabolites in the family pets of smokers. Carbon material, a byproduct of smoking, has also been found in these pets’ lungs.

As if we needed any more reasons to give up!

Quite comfortable, thank you!

Kidney Failure

Mittens getting the right balance

What do kidneys do?

The kidneys remove waste products from the blood stream, regulate fluid and electrolyte balance, maintain the acid-base balance of the body and remove toxins and drugs. They also help maintain blood pressure and stimulate blood cell production.

What happens when my cats’ kidneys fail?

Signs of kidney failure don’t appear until at least 70% of kidney function is lost. Chronic kidney failure, also known as renal failure, is the end stage of a number of different disease processes rather than a specific condition in its own right.

Kidney damage accumulates for years before we see any signs. Even then the early signs of kidney failure - increased thirst and urine production - are not easily recognised in our feline friends.

You may notice an increasingly wet litter tray if your cat is only indoors. However if you have other cats you may not pick up increased urine production in a single cat. 

Cats often drink from multiple water sources making it difficult to recognise increased  consumption.  

Other signs of kidney failure such as weight loss and poor coat quality are often put down to normal ageing. 

Often the first thing we see is a cat off her food, vomiting, depressed and dehydrated. The kidneys are already badly affected by this stage.

How do we diagnose kidney failure?

We diagnose and stage kidney failure with blood tests for the two waste products, urea and creatinine and a urine analysis to measure the kidneys ability to concentrate urine. We also  check the urine for protein loss or a urinary tract infection.

Tests for other substances like potassium, phosphorus and calcium as well as blood cell counts help us decide on the best course of treatment. 

Could it have been diagnosed earlier?

Because signs of kidney failure and rises in blood urea and creatinine are not evident until significant loss of kidney function has occurred early diagnosis is difficult. However, we strongly recommend at least annual blood and urine tests, as well as regular body weight checks. If urine concentrating ability is deteriorating or the creatinine is trending up we are able to slow down the progression of the disease with a special kidney protective diet. Any weight loss in a cat should be fully investigated.

What treatments are available?

After initial hospitalisation to treat dehydration and electrolyte disturbances, most cats are managed with a diet change and one or two other medications.

• Low protein and phosphorus diets lower the level of waste products in the bloodstream.  Try a few of the ready made kidney diets like Royal Canin renal or Hills k/d to find one your cat likes. Once your cat accepts the diet it must be her sole source of nutrition. Although if renal failure is advanced and your cat’s appetite is poor, any diet that the cat enjoys is acceptable.

• If blood phosphorus levels remain above normal after a few weeks on the special diet we add phosphate binders like Ipakitine to the food. Reducing blood phosphorus makes your cat feel better and slows progression of the disease. 

• Urinary tract infections are common in kidney failure and are treated with antibiotics.

• Cats with renal failure lose potassium in the urine leading to muscle weakness, stiffness, a poor coat and exacerbation of the kidney failure. The special kidney diets contain extra potassium but sometimes we have to add more.

• Severely affected cats need extra fluids. We can teach you to administer      subcutaneous fluids at home to reduce dehydration in advanced cases.

FRESH WATER MUST BE AVAILABLE AT ALL TIMES 

How long can I expect my cat to live?

Unfortunately aged kidneys do not recover. However, we can slow the progress of the disease and improve your cat’s well being with treatment and regular checkups. We check  phosphorous and potassium levels to see if your cat requires supplements and check for urinary tract infections at least every 3 months. This should give your cat a good stretch of high quality, active life.

Cat fights

Cats typically have a hate-hate relationship with any strange cat in their presence, yard, or environment. When new cats meet, they fluff up, spit, hiss - more like scream! - and the fur soon goes flying. While the brawl may only last a few seconds, that’s enough time for a few diseases to jump bodies. 

Feline leukemia (FeLV), feline immunodeficiency virus or cat AIDS (FIV), infectious peritonitis (FIP), or nasty bacterial infections are transmitted from cat to cat in saliva.

Outside cats, particularly unneutered males, love to fight. Most times they will end up with a nasty abscess.

What exactly is an abscess? It’s basically a pocket of pus under the skin. It makes a cat very ill because of the bacteria and toxins it releases into the bloodstream. He is feverish, goes off his food, hides and sleeps a lot.

Treatment for abscesses involves a general anesthesia, clipping and cleaning the skin, lancing the abscess and flushing all the pus out, placing a drain to allow any remaining pus, antibiotics and pain relief. Some cats are so sick they need hospitalisation and intravenous fluids for a night or two.

How do we avoid all this??

Desex your cat if he is still entire. Keep him indoors, particularly in the evenings and at night when the brawling usually happens.

Keep other cats off your property. A dog on patrol will soon despatch an intruder. Otherwise keep an eye out for a few evenings and frighten strays off with a loud noise. 

Catch the infection as soon as possible. If your cat has been in a fight bring him immediately for an antibiotic shot and stop the abscess from forming.

Vaccinate your cat against FIV, Feline AIDS. There are three shots in the initial course. A booster at the annual checkup and vaccine review prevents the virus gaining a toe hold.

Dr Kate volunteers in Northern Territory community

After the rains near the Alice in 2010

This isn't very catty news - but as animal lovers I know you will be excited to hear that Dr Kate is off to desex, deworm and treat camp dogs in Utopia's Indigenous communities near Alice Springs in March 2012.

She is going as a volunteer with AMRRIC(Animal Management in Rural and Remote Indigenous Communities) in a team of Canberra veterinarians.

She needs materials, equipment and drugs to desex, deworm and treat at least 120 dogs in a very intense week. So if you see cup cakes, calendars or raffle tickets for sale when you visit Hall Vet Surgery please give generously!

Snake season

Jonah reports that snakes are out and about again. He found one on Saturday night. His carers thought he wasn't himself on Sunday but when they came home on Monday and found him not able to stand they were sure he wasn't well.  His breathing was a bit laboured and his eyes were huge.
When we saw him he complained of his plight in a rather plaintive voice. His legs were very weak and he could hardly hold his head up.
This "floppy doll" weakness in a young cat at this time of year rang alarm bells for us.
Adventurous cats and snakes rousing from their winter snooze on a hot weekend are a recipe for disaster! Snakes are especially full of venom at the beginning of the season.
Jonah had some brown snake antivenom and has been on a drip to keep him hydrated. Cats paralysed by snake venom soon become dehydrated because they cannot eat or drink. Jonah has responded well and hopes to go home today!

Lily poisoning

All species of lilies are toxic to cats. Indoor cats with little choice in plant munching material are most at risk as they will try any cut flower that comes into the house. 

Any part of the plant - flowers, leaves or stems - is dangerous. Even lily pollen licked off the coat destroys cats’ kidney tubules. 

Lilies proven to poison cats include: Easter Lily (Lilium longiflorum), Tiger Lily ( Lilium tigrinum), Day Lily (Lilium hemerocallus), Asian lily (Lily asiatic spp.) and Rubrum Lily (Lilium rubrum). 

If you see your cat with lily on her coat, in her mouth or in her vomit don’t wait for signs of poisoning. The sooner we get it out of her system and start treatment to protect the kidneys the greater her chance of survival.

Affected cats vomit and are depressed within hours of ingesting lily. Some then seem to recover before starting to show signs of severe kidney failure a day or so later. Others continue vomiting, go off their food and get more and more depressed.

If emptying the stomach and medications to prevent absorption of the toxin are effective, the chance of recovery is excellent.

If your cat absorbs enough toxin to cause damage to her kidneys then her outlook is very poor. It is essential to seek emergency care immediately after ingestion of the lily plant.

Easy worming

Worming your cat has never been easier!  Many of you have tried the new spot on wormer, Profender, and been thrilled at how easy it is to apply and how little notice your cats take of it.  Anything to keep those sensitive felines happy!

Great cat enclosures

Many of us keep our cats indoors these days - for their health and to protect the lizards and birds in our streets. Today we found this terrific web-site on cat enclosures. There must be a protoype here that my cats would like!

Kitty dementia

Dementia, also known as feline cognitive dysfunction, is an age-related disorder of brain function causing multiple behaviour changes.

In cats the behaviour changes include:

• Yowling excessively and inappropriately
• Urinating or defecating outside the litter box and around the house
• Disorientation and aimless wandering
• Restlessness
• Changes in interaction with people or other pets such as aggression, irritability and clinginess
• Erratic sleeping behaviour: waking, pacing or yowling at night, sleeping less at night and more during the day
• Decreased grooming

Some diseases mimic cognitive dysfunction. These include hyperthyroidism, brain tumours, viral diseases, high blood pressure, chronic pain, arthritis, diabetes, and urinary tract infections. Many of these diseases exacerbate the behaviour changes of cognitive dysfunction, too, so we must check for and/or treat them before we confirm a diagnosis of cognitive dysfunction.

Some commonly used drugs such as prednisolone and valium also reduce brain function. Alternatives that reduce decline are often available.

Therapies

1. Diet: Anti-oxidants delay and treat dementia. Antioxidants include Vitamin E, Vitamin C, Alpha-lipoic acid, L-carnitine and beta-carotene. Fruits and vegetables contain many of these. Omega 3 fatty acids as found in fish oil or food supplements such as Nutricoat also help.

2. Physical therapy and environmental enrichment: Stimulate brain function and delay the onset of dementia with environmental enrichment and games. Try scattering or hiding food or catnip around the house, provide toys that require batting or rolling to release food, give opportunities for climbing, perching and exploring, trail ribbon or feathers along. Petting, brushing and massage stimulate the nerves and brains of old cats, too.

3. Your vet may prescribe medications to reduce inflammation, enhance memory or improve brain function.

Mischief ready for summer



Mischief sheds his winter coat

Nurse Tegan helped Mischief out of his winter coat and into his summer splendour this morning. Over winter he can't keep up with his long hair and it was matted on his sides and belly and up behind his ears.
Mischief is usually pretty laid back and purry but he asked for a sedative so we could clean up those matts behind his ears without hurting him.
He says it takes him a few days to get used to losing his winter coat each year but he soon appreciates the lighter easier style.

Worms in cats

Tapeworms and roundworms are the most common intestinal parasites of cats.

Tapeworms are long flat worms composed of many individual segments which look like grains of rice in the faeces.

Round worms are much shorter and rounder and produce microscopic eggs. Hookworm and whipworm are rarer but cause anæmia, loss of protein and gastrointestinal upsets.

Cats are infested with the flea tapeworm Dipylidium caninum by eating fleas carrying the tapeworm during grooming.  The tapeworm mature in cats and pass segments in the faeces which flea larvae ingest.

Cats are infested with the tapeworm Taenia taeniaformis when they eat infected rodents. Infestation with this worm is more common in hunting cats.

Roundworms, Toxocara cati and Toxascaris leonine, are common in young cats and kittens. Cats are infested with roundworm by ingesting worm eggs passed in cat faeces or by eating animals such as mice, which are infested with roundworm.

Most kittens are infested with Toxocara cati through their mother’s milk.

Toxocara cati can infest children if they ingest eggs attached to kitten hair or dirty litter trays.  The eggs hatch to larvae which migrate through the body and may cause damage. To prevent ingestion deworm kittens and cats as advised below, and dispose of litter and disinfect the tray with boiling water at least weekly.

Good quality broad spectrum wormers like Milbemax, Profender spot on and Drontal for cats are effective against all gastrointestinal worms.

Our recommended deworming protocol:

• Kittens from 4 to 12 weeks of age
• Treat every two weeks with Milbemax, Profender or Drontal for cats
• Young cats 3-6 months
• Treat monthly with Milbemax, Profender or Drontal for cats
• Cats 6 months of age and older
• Treat every three months with Milbemax, Profender or Drontal for cats

Feline Leukaemia

Feline leukaemia virus (FeLV) is an important viral infection of young cats in multi-cat households. Over the last few years infection has become less common.

What diseases are associated with FeLV?

FeLV infection suppresses the immune system making the cat susceptible to secondary infections and chronic diseases that would not affect a normal healthy cat. These include mouth ulceration, cat flu, and fungal infections.

Cancers of the white blood cells and solid tumours such as lymphoma cause 10-25% of FeLV deaths.

Anaemia and other blood cell abnormalities are very common in FeLV infected cats. Other FeLV-related diseases include abortion, fading kittens, diarrhoea, neurological or nervous system signs, and immune-mediated disease.

Around 80-90% of persistently FeLV-infected cats will die within 3.5 years of diagnosis.

How is the virus transmitted?

The virus is transmitted by direct contact between cats during grooming or sharing of litter trays and food bowls over a long period of time.

The virus is fragile and does not survive for long in the environment.

An infected queen passes the virus on to all her kittens if she carries them to term. However, this is uncommon as infection with FeLV usually causes infertility or abortion.

What happens when a cat is exposed to FeLV?

Not all cats exposed to FeLV go on to develop FeLV-related diseases. Most cats eliminate the virus from the body, although some remain latently infected for a few months before they  conquer the virus completely.

In cat colonies where the virus is endemic only 30% of cats are persistently infected with FeLV and go on to develop FeLV-related disease. These cats are responsible for the transmission of FeLV to other cats.

How do we diagnose FeLV?

A test at the surgery detects FeLV virus in the blood of a persistently infected cat.

A negative result is always negative. Your vet will assess the predictive value of a positive result by taking your cat’s environment, housemates and outside access into account.

Cats in the process of eliminating the virus will test positive. A second test performed 8-12 weeks after the first test confirms persistent infection.

Is there any treatment for FeLV infection?

There is no treatment that eliminates the virus from the body.

Infected cats should be desexed and confined indoors to prevent exposure to infectious agents and other cats.

Because FeLV-infected cats are more susceptible to disease, vaccination for the common viruses that cause cat flu and enteritis is very important.

We treat secondary infections and other problems like mouth ulcers as they arise.

Most FeLV-infected cats eventually die of their infection or we elect to euthanase them if they are suffering.

Can we prevent infection?

If possible do not house your cat with a known infected cat. Any new cat to the household should test negative for FeLV.

If all the cats in the house are FeLV negative, confinement indoors will prevent casual exposure to wandering cats with the virus.

Breeders may prevent FeLV infection by blood testing all cats and isolating infected individuals.

Vaccination of cats in contact with other infected or potentially infected cats is advisable. As with other vaccines, an initial course of two injections is required, and annual boosters are necessary to maintain immunity.

Cat FIV and AIDS

Freddy came in last week off his food and drooling a lot. When I looked in his mouth I found a red raw gums and mouth. No wonder he was so flat and uninterested in life. 

Many infectious agents contribute to sore mouths like Freddy's. Freddy tested positive to FIV  (Feline Immunodeficiency Virus), which predisposes infected cats to mouth ulceration.  His owners have 2 other cats and a baby and had lots of questions about FIV and feline AIDS.

FIV is prevalent in Australian cats but testing positive for FIV is not the same as having feline AIDS.

Feline AIDS describes the terminal stages of disease which may not occur for many years - or at all! A positive FIV test means that your cat has been infected by the virus.

Are my family at risk?

No. Although FIV belongs to the same family of viruses as HIV in people, it only infects cats. There is no risk of cross infection of either virus between species.

Are other cats in the household likely to be infected?

The virus is shed in the saliva of infected cats and spread by biting. Cats with a history of cat bite abscesses are more likely to test positive for FIV.

Spread between cats in a household is unlikely unless they fight. Normal social interactions such as grooming rarely transmit FIV.

The best way to minimise the chances of FIV infection is to confine uninfected cats indoors away from aggressive cats.

How is FIV diagnosed?

FIV is diagnosed with a blood test at the surgery which detects an immune response (antibodies) to the virus. If this test is positive your cat is infected.

Kittens with immunity passed on from their mother may test positive until 4 months of age. If a young kitten tests positive we retest them at six months of age.

Will my cat recover?

Once a cat is infected with the virus it remains infected for the rest of its life but not all infected cats  become ill.

What diseases does FIV cause?

Like HIV, FIV suppresses the body’s defences so that the cat is vulnerable to diseases it would normally  defeat. The cat is vulnerable to chronic or recurrent infections that fail to respond to regular treatment.

These include:

1. Inflammation of the mouth and tongue leading to appetite loss, drooling and mouth pain
2. Weight loss
3. Poor appetite
4. Fever
5. Signs of brain dysfunction such as aggression, unequal pupils, convulsions and behavioural changes
6. Swollen lymph glands
7. Unusual infections like toxoplasmosis, cryptococcosis, chronic flu, pneumonia, skin disease
8. Tumours especially those of the lymph system

The non specific signs of weight loss, poor appetite and fever occur in many diseases of cats and are usually unrelated to FIV. Cats with FIV are more likely to suffer from these signs and diseases more often and  be less able to throw them off even with treatment.

FIV positive cats have a shorter life expectancy on average than FIV negative cats.

Is there any treatment?

Secondary infections with bacteria or fungi are treated with antibiotics and anti-fungals but no specific treatment for the virus is available. Trials with anti-HIV drugs such as AZT have reduced mouth inflammation in affected cats but the cost and availability of AZT makes its use in general practice difficult at present.

Anti-inflammatory treatment reduces mouth inflammation and peps up the appetite in many cats.

Should I have my cat euthanased?

Certainly not on the basis of a positive FIV test!  Like humans with HIV, cats with FIV appear healthy and happy for a long time before getting sick.

On the other hand if your cat has succumbed to multiple infections, is no longer responsive to treatment or is suffering from a chronically painful mouth then euthanasia is the kindest solution.

How can I help my cat?

Confinement indoors of an FIV positive cat  reduces the risk of infection with other agents. It also reduces the risk of transmission of the virus to other cats.

A good quality, highly palatable diet as well as worming every 3 months and at least annual health checks will enhance the disease free period.

Infections require prompt and aggressive treatment.

How do we prevent FIV infection?

Desexing and confinement indoors, especially at night, reduces fighting and therefore the risk of infection. We recommend vaccination with FIV vaccine for all cats with access to the outdoors. Cats older than 6 months of age are tested for FIV before the first vaccination. A series of three primary vaccinations is given 2-4 weeks apart and then a booster is given annually.

Time to say goodbye?

Making a decision to say goodbye to a dearly loved pet and friend is never easy but at the end of life euthanasia can be the kindest and most humane way to go.

Only you know when the time has come. This checklist might be helpful:

•                 is your cat still interacting with you - lap time, dinner time - and with other people and pets in the family?

•                 is any pain, especially arthritic or back pain, well controlled. There is a limit to the efficacy of medications and good nursing.

•                 are the bad days starting to outnumber the good days?

•                 does she still have her little routines and habits?

•                 can she eat without assistance?

•                 can she get around to water, sun, bed, litter on her own

If you have done all you can to make your cat comfortable and happy but life is just not good for her anymore then you can feel more confident in making your decision.
