  1. 30 years ago we had a cat that was shot in the foreleg and had a sq bullet in the ventral abdomen. We fixed the fracture and sent him home. At recheck he had a distended bladder-pressure on the bladder caused him to urinate through his anus. Turns out the 2nd shot perforated his anus and his urethra and he formed a urethrocolonic fistula. A PU and colon repair ultimately fixed the problems.
