Yes she has a plastic fetish. Loves to lick plastic bags, any kind, she doesn't care. Anyone ever heard of this weirdness? she does not injest or chew the plastic; just licks.
Charvone does this all the time. No matter how many times we try to distract, redirect, or tell him to stop, he continues to have an obsession with licking plastic. It's very noisy, too.
Kismet tries to eat thin plastic like the ones for shopping bags, which is kind if pica-ish, but controllable thankfully.
Mo will lick nearly anything, but plastic is one of his favourites. He'll lick skin, wood, and plastic furiously. Actually, when he got a blood test done early this year, he was found to be slightly anemic, and licking lots of weird stuff can be a sign of anemia! I think in Mo's case, both his own personal weirdness and anemia play a part in the frequency of the plastic licking.
With 16 cats currently in the house I guess I have an answer for ALMOST everything...
Erik, one of our elders, LOVES plastic bags and whenever I get my supermarket delivery he'll be all over them - I watch out for the bags' handles though as in his enthusiasm he'd sometimes pull the handle over his head and around his neck and run terrified all over the place...
I once read that some types of plastic, especially the think cellophane types, contains a derivative of fish which supposedly attracts some cats. I don't know if this is true or not. I do know that we're seen some pretty weird eating fetishes in cats over the years here
