Reading all your posts, my lot (all 5 of them!) do exactly that as well! I'm recently into those lovely chocolates from Aldi (Mozer Roth - try them, they're yummy!!) and my cats just love playing with the wrappers (they're sort of tissue paper, with foil inside). I think little Romy, who's 10 now, is either getting a bit senile or going through her 2nd kittenhood - she's really behaving oddly. One minute she wants to go out, the next she wants to come in again. She's never been particularly affectionate, but recently has even been getting into bed with me (much to Monty's chagrin!) & purring like a dino! She's always been a funny wee thing - adores my GSD, Elsa, but hates all the others! She & Elsa are so sweet to watch, they snuggle up together, this tiny wee cat & a huge dog, but they really are the best of friends.
