Could it be the litter, they might need a good bath, or see below.http://220.127.116.11/search?q=cache...nk&cd=19&gl=usAnswer
I do have many suggestions for you. I'll walk you through my usual work up for a skin problem - basically everything possibly medical needs to be ruled out
prior to making a diagnosis of psychogenic alopecia (stress overgrooming).
There are 4 basic reasons why a cat
may be "overgrooming" -
1. Urinary discomfort - either a urinary tract infection, crystals, or a condition called interstitial cystitis.
2. External parasites
3. Skin allergy
4. Psychogenic alopecia ("stress grooming" - really it's more like OCD in a person - they are "compelled" to overgroom and no one really know why).
So - the medical diagnostics I would recommend are a urinalysis to make sure his urine is clear of anything that may possibly cause discomfort and check for the following external parasites: mites, ticks, lice, cheyletiella, ringworm. I think, however, that an allergy is far more likely in your cat's
Soooo - on to allergies:
In cats, allergies are caused by either fleas (most common), food intolerance (usually the protein source in the culprit), a contact type allergy (for example to cat
litter, but usually the skin is red and irritated), or something inhaled (for example, a ragweed allergy in a cat
is more likely to cause itchy skin than sneezing).
The pattern of hairloss your describe is typical of a flea allergy. You should try a different flea preventative, as Advantage is not always 100% effective. If your cat
is flea allergic, then even a single flea bite can cause a big reaction. Try switching to Revolution or Frontline. A contact allergy is less likely because your cat's
skin is not irritated, and environmental allergy is very rare. So this leaves food allergy.
With food allergy, normally this is an "intolerance" to a protein source that the cat
has been previously exposed to - most commonly chicken, beef, seafood (the most common ingredients in commercial cat
food). Cats can also be allergic to fillers and corn in their food. The most accurate way to determine if your cat
has a food allergy is to put him on an "elimination diet" This is a diet that consists of a novel, single protein and little else. He would need to be on the diet for 6-8 weeks and receive no other food - no treats, no flavored toothpaste, no flavored heartworm chews, etc. If his hair starts to regrow, then we know it is a food allergy and you can gradually start introducing other protein sources.
Only after all medical causes are ruled out
can you call it stress-related. Just remember, psychogenic alopecia is very rare. If your cat
does have this condition, there are medical and non-medical interventions you can discuss with your vet.
Best of luck to you and your kitty,
