Lump on cat's abdomen.

Species: Cat
Breed: DLH
Age: 11-15 years
My cat has a round, hard spot in her stomach. It has a red dot in the center It does not appear to be tender to the touch. There is some redness coming out from it. She is an indoor cat and approximately 14 years old.

Dr. Marie replied:

Thank you for your question. What you are describing does have me a little concerned. If your cat was an outdoor cat then I would be wondering if this were some type of an abscess from a cat fight, but if she is indoors then an abscess is quite unlikely unless you have other cats that she plays with.

The most common reason to see a hard oozing lump on the belly of a cat would be some type of a mammary tumor. Is she spayed? This is much more common in unspayed females but can happen in spayed cats as well.

There are several types of tumors that can affect cats in this area. Some can be treated with surgery.

I would highly suggest that you have your vet take a look at her as soon as possible. They can give you an idea as to whether this is something treatable and what treatment options you have.

I do hope that things work out ok.

Dr. Marie.

Thank you. I sent a picture of the spot. I thought mammary too, but it seems a little low for that. Thank you for your response.

Dr. Marie replied:

Thank you for sending the photo. I'm definitely still worried. The mammary chain does extend this far down the body so this is still my first guess.
