Why does my kitten have a lump on his neuter incision but acts normal?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Mediumhair | Male | neutered | 4 months and 19 days old | 4.2 lbs

My 4 month old kitten who was fixed 9 days ago, has a small lump on his surgical area. He is eating,acting, drinking, normal. No discomfort, no redness, no oozing. Scared it’s something bad but I read online it could be a suture reaction or scar tissue. Please help!

There are a couple of things this could be on Arlo's stomach. Yes it is possible that it could be a suture reaction, but it would be a little soon in the healing process for it to be scar tissue. Another possibility is a seroma. This is a pocket of fluid that can develop in the surgical site. Finally, it could be a hernia. The only way to know for sure is to take him into the vet to have it examined. Given that he is otherwise acting normally, it's not an emergency so I recommend taking him in Monday or Tuesday. Good luck, I hope this helps!

My cat got spayed on the 5th she has a grape sized lump under her incision is this normal or reason for concern to get her to the vet
I would guess that this lump might be scar tissue or a suture reaction, however sometimes a lump can form when there is an infection or even a problem with the internal incision. I would recommend having your vet examine Neyro's incision. If there is discharge tonight or if Neyro is painful it would be a good idea to have her examined by an emergency vet.

Is this umbilical hernia repair indision healing right? It’s been 4 days already. Worried about the big lump. Is the lump normal? Don’t know what it’s suppose to look like because I never had a pet that had hernia problem. This is a kitten that
This looks swollen but it can be a normal reaction to the dissolvable sutures under the skin. If the hernia opened up the swelling would be able to be pushed into the abdomen. If the swelling is firm it’s most likely a suture reaction. Be patient. This should go down a little every day and it may take a week or two to get flat. If it’s not going down or you can push the swelling into the abdomen then please take her for a recheck. If she was too active the inside stitches may have broken and the inside incision opened up. Then it would need to be closed again. Thanks for using Boop by Petco to help you care for Symphony.

My kitten just got spayed on Monday and she now has a squishy bump on her belly near her stitches should I be worried?
This sounds like it is likely a seroma (a fluid pocket under the skin), or a tissue reaction to the suture material - both of these are quite common in cats after spay surgery, and should not cause any serious problems. Less commonly, the swelling could be caused by an infection or even a hernia. If Leia is acting normal (eating and drinking fine, playful, etc.), you can monitor the bump until it's time for her stitches to be removed. Applying a warm compress like a warm wet washcloth to the area 2-3 times a day can help the swelling to resolve faster, as well as restricting her activity as much as possible. If Leia is acting very lethargic or not eating, or if there is any bleeding or yellow-green discharge from the bump, these may be signs of infection - in that case, I would take her to the vet today for an exam and antibiotics or other medication if needed.

I took my cat in to get fixed last week. They had to go into the abdomen to retrieve one of his testicles so he has abdominal stitches. Well since the first day of his surgery it's been swollen and it's a lump his belly. It doesn't act like it bothe
Hello. This incision looks normal for a week after surgery. Some swelling like you are seeing is normal especially if they are active and playing. It is normally just some inflammation of the muscle wall and subcutaneous tissue. It can take a few weeks for this to resolve and flatten out, but it will.

I took feral kitten to get neutered. Kept him in large trap overnight to let him recover from surgery. Today I noticed a lump on his arm. Called vet and they did not shave his arm or inject him on his arm. I was wondering what this big lump was. Mayb
Hi and thanks for posting on Boop by Petco! It is hard to say exactly what the lump may be. It could be an abscess, a reaction to an injection given, or a tumor. I would recommend Nugget see his veterinarian soon to have this evaluated. Your veterinarian may take a sample of the material or tissue from the lump to help determine what it is so it can be appropriately treated. If Nugget is otherwise normal, I do not think this is an emergency. I would just be sure to have this evaluated soon within the next few days. I hope this helps and thanks again for posting!

Hello, my 6 month old kitty was recently nuteured (March 1st). He now has a white circle on his right sack. It looks like there is no fur there and it's a little bump with a red dot in the middle. It's only on the one side. I was wondering what this
The picture is very hard to decipher, but I think it is the nature of a dark color fur and skin lesions don’t show up Well in pictures anyway. I am a little worried because it is different then the left side. I am hopeful that it is just a deep scab and is healing well, but I also worry it could be an early sign of infection. I would encourage you to have a follow up appointment with your veterinarian. In the meantime you can compress the area with a warm water and Epsom salt compress. Best of luck and I hope he improves soon. Thank you for using Pet Coach.

My adopted cat was spayed on 4/3. It’s now 4/22. I’m a little nervous as her incision site has a little lump by it. I adopted her and didn’t know she had gotten spayed so recently so I didn’t ask why type of after care she was getting. She’s acting f
The incision looks like it healed beautifully. That lump could be a localized tissue reaction to an internal suture. If the lump isn't bothering Stella, it isn't getting bigger or red, and she is otherwise behaving normally, you can wait until her appointment to have her seen. Best of luck.

This cat is 8 months old.I aopted her today.on her lower part of stomach there is a big lump which I asked abot it from her previous owner and she said it's because of her spaying surgery that they cut muscle.she licks it quite alot.I don't know when
Hi there and thank you for using pet coach to address your concern. This lump could be scar tissue and maybe due to a suture reaction from the stitches. This may also be a hernia but it is hard to tell. If it is firm, it is likely not a hernia and likely to be scar tissue. This is not contagious so I would not be concerned about transmission to your other cat. It would be best if a veterinarian examined this to ensure it is not a hernia. If it is scar tissue, it may reduce over time but could remain there for a long period of time if not forever. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

adopted a kitten 7 days ago was neutered 2 days before adopted, now today red and swollen looking at surgery site is this normal?or does he need med attention today?I will include picture
This is not normal, however it does not look infected either. Usually there would be the scrotal skin over this little lump of fat. Wash your hands well with soap, dry them, and then use thumb and first finger to grab the fur either side of it and gently pull it over the lump. If you can manage to do this, there is nothing else to do and it should heal. Only try this once. Jordan is probably licking, so it may be a good idea to get an e-collar for him. If this does not change by Tuesday or looks pussy or very red, then you should take Jordan to the shelter vet for a recheck.

Hello. I recently adopted a 2month old kitten who was spayed the day before I adopted with no ecollar. I noticed some licking around the incision and an ecollar was placed on her but it appears a small bump (pea sized) formed and pink coloring. No fl
Hi, thanks for using Boop by Petco. Monitor for an redness, drainage, increase in swelling or pain along the incision. Not eating or lethargy are also signs to watch for. This may be a suture reaction, an inflammatory reaction to the sutures used. If concerned you may want to call the shelter to find out if their vet or technician offers rechecks of their surgical patients.
