This is an awesome idea! I would love to buy one! Whoever made the comment, “how you would clean the cat poop out” is ridiculous! Litter train your cat and that is how! Also, a three year old getting stuck? Really!? You don’t keep your eye on your 3 year old at all times? Maybe wait until your kid is older before getting one. I say you should make them for people like me that don’t complain about EVERY little detail on how something can go wrong!
