Query: Hamster Escape

This product might be great for some other small animal but not hamsters or anything else that can climb easily. My hamster can (and does) get out within minutes of putting him in the playpen. He can climb over and has also figured out how to unlatch the hooks that hold it together. It is a cute idea but unless you plan on sitting next to it and combatting your hamster I wouldn't recommend it to anyone.
