What's this growing pink bump under my cat's chin? Is it serious?

Updated on September 23rd, 2025

Pet's info: Cat | American Shorthair | Female | spayed | 12 years and 9 months old | 12 lbs

My cat has a large pink bump under her chin. It doesn’t seem to bother her but it has gotten a little bigger in the last month or so.

Pets can get many types of lumps and bumps. Most of these tumors will be benign but some will be malignant and you can't tell by looks. Here is a helpful link discussing the various types of skin masses in general:

Since you are noticing the mass changing, I do recommend to have it checked out to be safe. The doctor may recommend to aspirate the mass to examine the cells under a microscope. That is one of the best ways to know what it is and if further action is needed. Hopefully it's nothing serious.
