I've thrown my old litterboxes away when they broke. I use the covered kind and the latches would break over time. Now I've found a better type of litterbox from Petmate that doesn't have latches and they're very sturdy. I hope to have these around for a long time. I'm currently using only 4 boxes and 2 are covered and 2 aren't so the cats will be able to choose which kind they'd like to use.
