I went downstairs to get a drink, only to discover I have a random cat curled up on my sofa. So I went up to it, nudged it and it just looked at me innocently and went back to sleep. It definitely does not belong to me and I've never seen it before. My own cat is on the top stair of the ladder we have up, and is looking quite freaked out by it all.
Do I let it lie there looking cute and comfortable, leaving my own cat [who's currently quite scabby/dribbly/uncute] to balance itself on a ladder until the former cat is no longer feeling sleepy; or do I go and throw it out, feel mean, but stop my own cat from hating me?
