Every chance I get!! Mommy goes out of her way to put them out of my reach but I always manage to find SOMETHING that is plastic so I can chew on it. Trash bag, whatever. That's how I lost one of my 9 lives--mommy caught me chewing a bag once and actually pulled about 6 inches of plastic out of my mouth. I don't know why I chew those things, I just do. Maybe to bring up fur balls, it does seem to help. Anyone else like to chew on bags?
