Cat with bump on skin.

Species: Cat
Breed: American shorthair
Age: 2-5 years
My 5 year old cat has a small bump on the back of his neck. It moves with the skin and is about the size of a pencil eraser. It does not look red or irritated and does not seem bothersome to him, even when touched. What could it be, and should I be concerned?


Online vet, Dr. Marie

Dr. Marie replied:

Hi and thanks for your question.

It's always hard to talk about lumps online but I can give you a few of my thoughts.

When a cat has a lump I always want to have it checked out. There are a number of skin tumors in cats that can be quite serious and are much easier to treat sooner rather than later.

With that being said, a lot of the time these lumps turn out to be fluid filled cysts that are not bothersome but simply cosmetic.

I have seen some cats that have what was thought to be a wart but turned out to be a tick so this is a possibility as well.

In any case I would advise having your vet take a look at it. They will do a test where they put a small needle into it to draw some cells or fluid out and they should be able to tell you whether it needs to be removed.

Hope all is well!

Dr. Marie.
