Cats like wool and will eat it. No wool sweater is safe from a wool eating cat. Not funny
My mil lost 10 sweaters that each had a hole eaten out of them by her cat. They were gifts stored in a back room
My wife knits and also spins her own wool, so we usually have some raw wool lying around. We had a laundry basket that had seen better days so we filled it up with raw wool my wife wasn't going to use and left it out for the cats to use as a bed. They had a reaction similar to Taz the Kitten. That's what's funny.
