I have two cats and have used this for years. But the last container that we bought was horrible! It turns to a sticky wet gray clay that has to be pried out of the litter box. It sticks to the cats paws, which they then track through the house.
This evening I checked, and there were actual puddles of urine floating in the bottom of the litter box. I don't know what they did to change the formula, but it's not working. Our next kitty litter purchase will not be Tidy Cats!
