About once every three months, a brand new roll of tp or paper towels is completely shredded. I think it's one of the M and M boys.
If I leave newspapes on the floor, one of them occasionally decides to start shredding. I'm pretty it's the chubby brown tabby. She used to shred papers constantly when she was a kitten. She'd like on her side with the papers between her front paws, and use her teeth to peel off shreds of the paper. It taught me to keep the papers picked up (most of the time, anyway). Most everything else she leaves alone. She also used to get into the medicine cabinet if I left it open, and knock down small bottles, like eye drops, and bat them around and lose them. It was a problem with my prescription drops. It also taught me to keep the medicine cabinet closed. I learned so much from that little cat! Of course, now that she's nine, she is much more mellow.
