My male acted completely normal when I got him home. There seems to be two differing points of view regarding antibiotics after neutering. My vet felt that effects of the antibiotics would counter his recovery so she didn't prescribe them. Big mistake. He developed a small abscess after 3 weeks. If I ever neutered another male, I'd insist on an antibiotic, along with a probiotic. He was prescribed Metacam for pain. My vet didn't charge me for any follow ups and Rigatoni recovered. Keep his cage immaculate. I used and still use fleece and changed it multiple times a day. You can dilute chlorhexidine with water to a light blue color and rinse the suture site once a day. That will also help to keep the area bacteria free. Don't use bedding that might stick to the wound.
