@Katie-and-Chris2 we host cats/kittens and dogs. We have hosted birds and guinea pigs.
The only damage we have ever had was from a dog trying to chew through a door when the owner locked him in the laundry room for hours. We have had zero issues with cats. I doubt the owners would "crate" a kitten in the same way as a dog, but if they have a "kitty condo" large enough for a litter box and food to go in, they may want to err on keeping the little one inside when they are gone just for its own safety. Kittens can be full of mischief but are also tiny and can get hurt if the wrong thing falls on them in an unfamiliar space.
The cat damage argument is something we have never once had an issue with. Not. Once. Having owned cats myself it takes a while for the average one to shred furniture. A weekend stay wouldn't do it. If you are planning on hosting pets a thick leather sofa is probably the best thing to have as well as easy clean hard surface floors. We leave Nature's Miracles for accidents which helps a lot too.
My only other cat hosting advice is to make sure the litter box has something under it to catch stray litter. We ask that guests keep the litter box in a specific room so that the cleaners have an easy time identifying where to make extra effort.
