How Soon After Spay Does a Female Cat Urinate?

A female cat generally urinates within 24 hours after spay, with the time by constitution. If she still has not urinated 1 to 2 days after surgery, take her to a clinic. Anesthesia before surgery slows internal metabolism and affects urination, but normal return is within 24 hours; if none after 24 hours, think urinary stones or kidney failure and check promptly.
