I use Purina ONE Sensitive Systems for all 4 (ages 3-15) of my cats. I have been feeding it to my 15 yr old since it came out on the market. They all love it; and have never had any health problems at all. The reason I first started using it was that I was complaining to my vet about cat poop...
The problem is not the litterbox itself. My cats don't really kick out much litter. My problem is that the litter is sticking to their feet and being tracked all over the house! I find it in every single room, on the beds ...even on countertops (I have one very naughty kitty!).
I love the new...
