Slightly off topic: in the wild, cats don't walk with their tail in the air, only kittens do. The theory is it makes them easier for their mother to see them in long grass. So when your cats have their tails in the air when you are around, it's because they are in kitten mode, and you are their mum.

btw, I've never seen a skunk, except in bugs bunny cartoons and the occasional photo. I'd definitely be picking up those adorable kittens.
