I think a cat has been coming in the cat-flap - I mean a cat other than ours - and spraying somewhere in the house. I can't figure out where! I know where it kind of smells stronger but I can't pinpoint the location. I have one of those UV flashlights which is fun but hasn't helped. What am I looking for? How do I find it?
I don't think it's our cat - this started recently and we've had him over a year and not had a problem before. Plus he's been neutered.
Help me... it's embarrassing when people come in and you see them wrinkle their nose. Plus, yuck.
