So I picked up the breeze litter system to try out for Finn because I was getting fed up with testing out different types of litter and disliking them all. Plus, the cats had taken to using his litter box if there was something in there that they could use to cover (like pellets, shredded paper, etc.)
I discovered it makes a wonderful box if you don’t use the pellets they provide! The grates are small enough to catch even the tiniest of poops and the pee pad can hold A LOT of urine. I change the pad every 3-4 days and empty out the box daily and have no problem with smells. I’ve read that you can use cheap doggy pee pads instead of the expensive 4 pack tidy cats sell.
I’m really impressed with this box… and since there is no “litter” there is nothing to tempt the cats.
You can see how small the grates are. they’re flush with the plastic so there’s little chance of sore hocks

Here’s a link if anyone wants to read up on it:
