Lack of appetite β don't wait more than a day before ringing. He's already down from 4.85 kg. A cat that stops eating properly risks hepatic lipidosis.
Lack of faecal matter β nothing since the 20th/21st, and opioids plus gabapentin are constipating. A constipated cat straining looks almost identical to a blocked one: check whether anything actually comes out.
Blood in the urine β a small amount is expected early, up to about a week. Increasing or heavy is not.
Swelling, bruising or bleeding at the surgical site.
Leaking urine around the house.
Excessive licking β cone stays on 24/7. Licking introduces infection and risks a stricture. If he's at it constantly, that's what the buprenorphine is for.
Vomiting or diarrhoea β stop the Metacam and tell them. Note clindamycin can also cause this: ask them now which to stop first, rather than deciding it at 11pm.
Emergency β no waiting: straining with
nothing at all coming out.
Post-op this means stricture rather than a blockage, but it presents identically and is just as urgent.
Same-day emergency vet.
