Don't Get A Sieve Tray!
First time I've tried dissolving 'sand' litter, and so far I'm impressed. They really do trap in the odor compared to all the other more expensive kinds. However; some people say you should get a Sieve Tray for this kind of litter. I did just that and found the extra steps in cleaning the litter not worth the regular maintenance. It just clogs up the little vent holes. Buy litter bags, drape them over the tray and shift the dissolved sand to the underside. Much easier and effective.
