Query: too flimsy to work

THE GOOD:It's relatively cheap. Unlike some other designs, it fits most American toilets.THE BAD:It's made out of cheap, thin, flimsy, plastic. When loaded with litter, it bends and warps with every move my cat makes (and he only weighs ~10 lb). It's clear that my cat does not trust the thing to support him, and so a month into the training it's been an uphill battle with many accidents all over the bathroom floor. Also, the bin for the litter is very shallow. It can only be filled with about 1/2 inch layer of litter. This might be ok for later training stages, but initially the cat feels cheated when he's used to digging around in a big litter box. Long story short, this kit is going in the trash and I'm placing an order for a more expensive, solidly-built one.
