Hi, I recently built a bigger litter/kitchen for my two females guinea pigs. One of them LOVES to chew on the coroplast. They have so many chews and even a little house that they can eat. I went ahead and bought some of those plastic edges for clear binders. However, my guinea pig ate it already. It's literally been 1 hour since I put them. Any ideas? I'm scared she'll eat more plastic and get sick, should I take it off?
