Review on Marshall Ferret Animal Playpen Panel by Gina Estevez

It was several months of work before my rat figured out how to get away from it even when covered from above and below. She is a master of escape, nothing can stop her! She bit off the entire rim of the bottom lid. Then she climbed onto the top of the playpen, pushed off the top cover and climbed out. The animal is smart enough to run away. After seeing her squeeze out the top, I stuck a bobby pin in to tighten the lid, after which she started chewing on the hole around the clip to make her run away! new tight tight lid because my rats chew off the strips. Edge, now destroy the top cover and crawl out. :( I don't know what to do, this is the only cover available for my 11 panel player and I am not satisfied with this product.
