Automatic Litterbox Central

I have a large snowshoe cat that loves to eat plastic, DHL Yellow plastic bags, home depot bags , lowes bags, giant food bags,
Large Green 55 gallon plastic trash bags, but he will not eat the white one I use for my kitchen trash can. Is this a lack of a vitamins, behavioral problem, WHAT I ASK IS IT! I am sure glad he does not eat the catgenie pellets!

I think it could be a texture thing. I have one cat who loves to chew plastic bags just like your kitty, one who likes wires (yes we tried all the bitter sprays and he doesn't care and yes he electrocuted himself once and now is paddling his boat with only one paddle), one who likes cushions or pillows (she destroyed our new Lay-z-boy couches... good thing she is so cute), one who likes paper and the corners of all my books, and one who likes wood (think all our door jams in the house). I think they all just like to chew whatever feels good on their teeth and gums and it is a personal preference on what that is. We recycle the few plastic bags we always seem to end up with so I keep them in a closet and she has moved onto anything plastic in the house.. such as my exercise bike pedals and seat What can you do.
