I also have a cat that likes to lick plastic. It doesn't matter what the plastic is on (toilet paper, water bottle cartons, etc.), he just licks them to death. I've asked about it at Vet visits, but he's in good health. I guess it must be like bitting your nails, just a habbit.
Just bought one of those Litter Maid electric litter boxes. My large cat started pooping on the floor by the box. I was a bit puzzled until I started reading info on this website. I put the old litter box next to the new one and so far, I haven't had to remove poop from my floor. I suppose...
