Catnip and some paperbags or boxes to crawl around in...lol. the in the house (tree house) stand is a hit too.
Alot of Cats are easy, unless you keep messing with them lols
Teenagers? The cats do not ask for an allowance, nor do they want the car on Saturday night and YOU CAN GET THEM FIXED!
I would hate to watch cats for a week ! I have other things to do ? Lol
You must be a saint to take on this responsibility. My neighbor took in another neighbor's dog while they were on vacation ...the dog got loose and was hit by a car.
All that and they won't cooperate when you try to walk them around the block either
