Anyone ever have a cat with a "plastic deficiency"?

We had one who, if she happened to find a plastic grocery bag within reach (and we really tried not to) would just lick and lick and lick and lick and lick endlessly on it.

Bring in the groceries, put them on the floor in the kitchen while bringing in the rest and then putting them away, and Peaches would be right there, lick lick lick lick lick....never ever in her 19 years saw her stop licking on her own, only when we took the bag away.

Ribbons (on gift packages) were also fair game, come birthdays and Christmas we had to barricade away any presents with a bow on them or ribbon wrapped around....
