I feel good about using this washable litter. It makes me happy to help the environment. I used to use scoopable cat litter and I went through it (with two large cats) like crazy. I HATED hauling the giant tubs of it into my cart at Costco and then into the car and out of the car...then trodding into thte house with them...Yuck. Not to mention the storage space it took up, and the guilt of throwing them away after just one use! What a waste! These little boxes are expensive, yes, but it's smaller than a box of cereal and it lasts months (my cats don't have the hardest waste in the world, so I go through more than most people probably do). Great invention! Thanks!
