Query: A good idea in theory.

In theory, the potty is a great idea. In reality, it needs some tweaks. First of all, the lid makes it too small for a Syrian/Golden hamster (the larger guys). No problem, take off the lid right? Well, the rounded corners of the base make it so the hamster aims its butt at the end of the base, overlapping it and thus peeing OVER the end onto the floor of the cage. If the potty was square and fit flush with the corner of the cage, it would be perfect. Well, at least I can use the little scooper that is included to get into the cage corner and scoop the pee shavings.
