This is the system we use at Buffalo Creek Farms. It eliminates cat litter completely. We order our pads and pellets on Amazon in bulk as a grocery item. On Amazon the pellets and pads in bulk is about a 6 month supply. The boxes are about 20x12x6 so not huge to store. Best it is free shipping and UPS just delivers it when you need it. All kittens start on this system because very young kittens like to put everything in their mouths and eating regular cat litter is not good. The kitten are introduced to regular cat litter between 6 to 8 weeks. That way when they go home if that is what you choose they will know have regular cat litter is. We do not recommend starting any kitten with crystals corn etc.. simply because they will not know what to do with it and may mistake it for a sand box to play in. We never recommend the crystals as they are toxic. The kittens always have access to the breeze system some prefer it because it is cleaner. The kittens do not end up with litter stuck on their feet. We prefer it because a few pellets are easy to sweep up. Cat litter gets every where is is very hard to get up. Regular cat litter is also heavy to lug in and out of the cattery. We find the over all cost equivalent to a good kitty litter.
