Nope, wouldn't work for me as a guest. And those cats are going to pay you back with a proper swift scratch with freshly-sharpened claws. If you want a cat sitter, this is the wrong website, @Catriona24.
@Catriona24 I wouldn't trust a complete stranger to take care of my pets. There was a story posted on here a while ago where someone did this, and the person never fed the cats. Luckily, they were okay, but I wouldn't rely on a guest to do this type of thing. There's noting in Airbnb's rules from preventing you from doing it if you want to - just make sure you're super clear in your listing that it's a condition of booking - but I would recommend it.
