I just gotten my 6 month old kitten back from his neutering, and have been checking up on his incisions for the past hour. The vet didn't use stitches (I believe she cauterized the wound), but one of the incisions looks a bit fresh (red and open.)

There appears to be no bleeding or discharge however, nor do I see any swelling yet. He just gotten the surgery done today a few hours ago. He smells kinda stinky though, although that may be because he hasn't groomed himself much down there as the anesthesia hasn't worn off completely yet.
Oh she already injected him with antibiotics and other medication which she said will last for 3 days luckily. I think I'll give her a call though in an hour if things don't improve. :O
