Hey, thanks for the advice!! i looked at it today and seems to be already starting to heal pretty nicely without bleeding or pus.
I'll contact the vet today just to be sure.
So on Monday I took my 6 month old kitten to get neutered and yesterday I was looking at the incision and it has opened a bit on the top?? it's not bleeding and didn't see any discharge( the yellow color is from a spray) so I don't really know what to do.
