we recently got one of those cardboard cat stratchers for our cat, you place catnip in the crevaces to intice the cat to use it. she has used and abused it to the point of turning it upside down and shredding it. now that we cleaned up the mess, and placed it right - side up again she is just sitting on it like its her bed. makes me think she's addicted to the catnip and the scratcher is the "patch" like smokers use.
