My 8 year old cat is sick

Question
My cat has loss of appetite and loss of hair above eyes an ears.A fowl odor from her mouth also. What can be wrong with her?

Answer
You need to get your cat to a vet. At 8 yrs old, she could have very advanced gum disease, or a bad tooth, ulcers on her tongue, cancer of the mouth etc. She could also be in kidney failure.

That will manifest eventually with an odor in the mouth (from the uremic poisoning) and loss of appetite. She may be drinking a lot of water and using the litter box more.

In either case, any time a cat stops eating it's very serious. Get her to the vets tomorrow.
