My cat has red, bleeding stomach bumps. Should I take her to the vet?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 25 lbs

My cat has some bumps on her stomach, they're red and round and recently she has started to bite them so in turn there is some bleeding. I read online that it could just be fatty tumor, what can I do? She also lost a tooth a while back, her gums seem to have some blackness, is it concerning or nothing to worry about?

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. Based on its location, this could also be a mammary gland tumor which in most cases are malignant. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!
