We've been through ALL the liter boxes out there... The ones with tops, the ones without. We have dogs, so of course, we have THAT problem... They want to treat themselves to a "snack" (gross, but TRUE!). Of course, we wanted to stop them, so we tried the Clevercat Top Entry Box.
Well, it works and it works well. The dogs (a Whippet and a Lab) can NOT get into the box. The cat enjoys it (he likes his privacy!), it contains odors pretty well when changed regularly and the best part? It's the easiest to clean box we've tried. Not sure what it is about it, but it's so easy to wipe down or hose off for a deep cleaning.
Even if you don't have dogs, I highly recommend this litter box! It’s even stylish and fits well in any room.
