I took my kitty to the Vet this morning. When I returned from vacation I noticed that her bum was red. At first I thought it was blood but upon further inspection I noticed that she had holes around her anus filled with puss. I squoze them like zits and the expelled the puss. When I took her to the vet he told me they were scent glands and that they may occassionaly get clogged. He said this happens more often in dogs than cats, but having raised both, I've never seen or ever heard of this. He squoze the rest of the puss out and gave me some medicine to squeeze into the two holes on each of her scent glands since her behind is so red and irritated. I was just wondering if anyone has ever heard of this happening before to their cats, and I wanted to find out how often or even how this happens. My cat is an indoor cat and I don't know why this would happen to her. I've had her almost 4 years and this hasn't happened before. The vet told me to just squeeze them out myself next time this happens. But what about medication for inflammation? Any suggestions on what to do next time this may happen so I don't have to spend $50.00 at the vet?
