Weight loss in cat.

Species: Cat
Breed: Mix
Age: 11-15 years
My cat use to be really overweight. About a year ago he started to get sick a lot so we tried changing his food. Since then, he has rapidly lost weight and is now starting to show several other symptoms. He is shedding his hair a lot more, his purring is not normal, he's a lot less aggressive than he used to be, and he doesn't clean himself.

I know he's in bad shape and we haven't had him in to a vet in years. I am just wondering if there is anything we can do to make him more comfortable and if there is any hope in improving his condition.

Thanks!

Dr. Marie replied:

I'm sorry to hear that Michael is having these problems. There are a number of conditions that older cats can get that can cause the symptoms you described. Some of them are treatable if we get to them early enough so it is a good idea to have your vet do some bloodwork on him.

One possibility is hyperthyroidism. Cats with this condition will tend to eat well but still lose weight.

It is also possible there is a problem with his liver or kidneys. Some of these problems are treatable, but some we can only manage with medications for a short while.

Diabetes is also a possibility especially if he is drinking and urinating a lot.

There are other possibilities as well. Your vet will likely do a thorough exam and some general bloodwork to determine what is going on.

I hope he does ok!

Dr. Marie.
