Lump or bump?

[Musiaka]

Is it common for cats to have a slightly bumpy texture on their bellies?
Musiaka's belly feels a bit uneven at places - nothing sticking out and it's not a growth. I noticed some bump, that I can only identify if I press a bit harder on his stomach (he doesn't react to it/no pain) but I don't know if it's just some irregularity or some tumor starting to grow. I can only feel it if he's laying down on his side.
Do your cats have any bumps?

Are you sure it isn’t his nipples?

No, not the nipples - its more like a slight roundness on his belly in one place

It could be multiple things, one of my cats has a lump on her stomach area, we were worried about cancer, but it turned out to be a hernia that's not dangerous at all unless it opens up, but that's unlikely to happen if the cat is never going to give birth for example. If you are worried about what it might be, ask your vet about it the next time you take Musiaka.
