Dog ate chocolate?

Large abdomen in cat.

Species: Cat
Breed: orange tabby
Age: More than 15 ye
We have an 18+ year old cat who is thin and bony, but has a 20" diameter potbelly which appeared within 2 weeks. Several months ago we started adding 1/2 can of wet food per day to his diet in an effort to help him gian weight, but stopped that several weeks ago when we saw his belly growing. His belly however, has not stopped growing.


Online vet, Dr. Marie

Dr. Marie replied:

It sounds like it is time for a vet visit. Unfortunately when an older cat starts to get a large belly it is usually a sign of something serious.

It can be a build up of fluid. The most common reasons for fluid to build up are because of cancer or serious liver disease.

Another possibility is a very large tumor in the abdomen.

By far the best thing you can do is have your vet take a look and determine what is going on.

I hope he is ok.

Dr. Marie.
