What is this hard, sensitive lump on my cat's leg after a fight?

Updated on September 23rd, 2025

Pet's info: Cat | Norwegian Forest Cat | Male | neutered | 8 years and 6 months old | 9.91 lbs

Hi. I have an indoor/ outdoor cat who recently got into a fight with another cat outside. He had a cut on his leg and heel that healed quickly. I cleaned it regularly. But I noticed 3 days ago that on his heel is a hard lump. I can see that it's covered in crusted blood that I didn't see right away as he is long-haired, even his legs and feet. The lump is sensitive to the touch. I try to clean it but he doesn't like it. It doesn't seem to be changing shape or size.

It sounds like Kit has either an abscess or cellulitis. I recommend to take him in to the veterinarian's office today for an exam and likely antibiotics as well as pain medication. The doctor may recommend to drain the abscess as well (assuming its not cellulitis). Infections after cat fights are very common. Hope Kit starts feeling better soon.

My cat has a purple-red lump on his side near his leg. Is it serious?

This could be a bruise (hematoma) or a developing abscess. Your kitty could have gotten into a fight with another cat. I would observe it. It it starts hurting your cat or is fluctuating, or if your kitty is getting lethargic or stops eating he needs to be seen by a veterinarian for an exam.

My cat has a smelly, painful lump from a fight. Is it an abscess?

Yes, that appears to be an abscess. What you are smelling is infection. Chances are it won't clear up without oral antibiotics. I suggest you get him to the vet for an exam and to get some antibiotics. You can try applying a topical antibiotic cream/ointment but it is rare for that to actually work on it's own. As a side note, male cats that are not neutered usually get into a lot of fights so if you don't use him as a breeding animal you may want to have him neutered to minimize the chance of this happening again.

My cat is limping and has a lump on its front leg. What should I do?

Hello. I would have this looked at by your vet tomorrow. The most common thing we see in cats are bite abscesses & it is really amazing how hard it is to sometimes find a bite wound. A cat's bite can leave a tiny needle like puncture & an abscess can begin to develop within hours. It can be very painful & make Buddy feel sick. Your vet can quickly determine if this is the cause of his lump, lance & treat it & Buddy will be feeling better very soon. Thanks for using Petco Pet Education Center, formerly Petcoach.

Found a red, painful lump on my kitten's leg. What should I do?

It looks painful and infectied. It may be a tumor or cyst or even an old wound that is an abscess and starting to open and drain. Clean with with warm soap and water then applly a warm compress to help the swelling. Make sure she stays confined so you can watch the area. If it ruptures and drains, it will actually be not as painful but just gently wipe the area if this happens. She does need to see a vet for antibiotics though.

My outdoor cat has a hard head lump and is acting sick. What is it?

It's likely that this lump is an abscess from a fight he had outside with another cat, you will need to take him to the vet in order to get it checked and treated, if it is an abscess it will need to be lanced and clean under sedation, he will also have an antibiotic injection to treat the infection.

My cat's burst abscess from a fight: When should I see a vet?

If Felix got out, he may have gotten into a fight with another cat, gotten bitten, and it turned into an abscess. It sounds like the abscess has burst, but if it's painful, he does need to see a vet. I would take him into one first thing in the morning.

My cat has a lump after a fight and antibiotics. Is it an abscess?

Hi. Yes, this could be an access. I can't say that for sure, but if the bacteria are resistant to the medications prescribed, an abscess can still form. I recommend getting her rechecked so you can find out what that lump is.
