Ok this is weird to be posting it but I figure we are all friends here, why not share some tips and tricks for things other than software.
I've been using* this new cat litter system, Breeze, for the last couple of weeks and I am extremely impressed with it. It basically uses special reusable pellets and a special liquid absorbing pad (like a diaper) in a bottom compartment to collect liquid waste.
It seems to live up to it's promise of not having any real odor, and it's hands down the easiest litter i've had to clean and maintain by a very wide margin. The improvement in my cat's life has to be significant since the litter is always clean now and it never was before. Nothing outside the box either (i've never used clumping clay litter since the sandy grains drive me crazy. I guess if there was one negative it would be that the solid waste might smell a bit until you remove it since it just lays out there in the open and doesnt get buried.
About Price: Basically they suggest you replace the proprietary pellets once a month, and the proprietary pad once a week. You can buy these in bulk from Amazon and I think I worked out the price to be about $14 a month in total costs if you do that. I was spending more than that on the litter i used previously (Feline Pine), and this is far superior, and also there are no liners to buy either.
Also, the supplies take up vastly less space than traditional kitty litter supplies since it uses vastly less litter than traditional litter boxes.
*Technically it might be more accurate to say that my cat has been using and I have been maintaining.
