Oh yes, the paper craze faze. Every kitty has to go through it. A brown paper bag with a tease hole in it helps, but you really need gloves if you use a finger, or else, shredded finger. Our cats always loved just a piece of paper all scrunched up and tossed to be batted around like a ball, that got them out of the tear it up phase for us anyways. Still though on occasion they all revert.
