he can go outside only to go potty for the next 10 days. no running around like a wild man, no long walks, no jumping on the furniture or going up and down alot of stairs. this is only to prevent the stitches from poping. Some vets give pain meds for the first day or two, some don't. neuters are no big thing usually, and the incision is soooo small. make sure he gets his antibiotics every day and be sure to give him some extra lovings
he'll be fine.
