Yes, it is true, yours and mine and those of the others who wrote answers to your question are not the only cats with this plastic predilection!

My calico princess, Julie (meow!) likes to LICK anything plastic, from bags to plastic storage containers and laundry baskets, even certain photographs.

I try to keep all these items away from her. I am not worried about her damaging them as much as I am about them hurting her...in terms of her ingesting dirt, chemicals or even a stray piece of plastic that might come off and lodge in her throat--my worst nightmare.

So I would advise keeping these items away from your cat, especially if he or she actually tries to bite or eat the plastic items. Choking is a real possibility in such cases...
