Our cat likes to wee right at the corner of the litter tray, and sometimes it goes over the edge by accident. We have puppy pads down around the tray to protect the carpet. Somehow, a horrible cat wee smell has got into the carpet and the room his litter tray is in stinks. Like eye burning cat pee smell. We tried cat wee smell removing spray, that did nothing so then 1001 carpet spray (usually works!) no joy. Washed with bio washing powder. When that also didn’t work used a rug doctor type carpet cleaner. Smelt a bit better but not gone. (All this was over about a week/10 days not all in one day btw!) Have aired the room, taken out as much furniture as possible.. still smells.
Is there anything else we can try?
