Pet's info: Cat | Mixed Breed | Male | neutered | 2 months and 6 days old | 11.8 lbs
So my cat Woofie has this lump on his head. He’s about 10 weeks old and we noticed it a few days ago. It hasn’t grown very much in that time. He is very rambunctious and plays rough with his siblings. We often hear them slamming into things even after trying to kitten proof. He has the same appetite playfulness and personality his pupils dilate properly and he wants to mock fight all day. We’ve never seen blood on him. I’m just worried it’s an abscess or a malignant tumor.

Cute kitty. Any swelling on the body that does not go away within a few weeks, that is somewhat soft and not causing any pain, is likely a hematoma. Hematoma's come from trauma that has burst a blood vessel underneath the skin. It can take 1-3 weeks for the blood to then be slowly absorbed back into the body. If this is a hematoma, it should go down slowly. If it happens to not go away, then yes it is best to have your vet take a look at it for other possibilities (i..e cyst, abscess, etc). I hope your fur baby Woofie resolves this swelling soon. Best wishes and take care.
