Help! My cat loves plastic bags

I have 2 cats. Only one cat loves to lick, and tries to eat almost anything made of plastic, especially plastic bags, shower curtains, food wrappers, etc. Is there a chemical on the plastic that makes it so tempting? Is this a dietary problem? What can i do to stop this behavior besides entirely eliminating plastic? Plastic wrappers and bags seem to be everywhere!

 

Answer from Dr. Gaylord Brown:
This is a personal obsession, not a deficiency. Try to direct the cat to more appropriate toys when she is after the plastic. The bags, if eaten, may cause a problem.
