Very poor product
I like a lot of Tigerino’s products, and bought this one by mistake but figured we’d give it a try, horrible stuff. Clumps set like plaster, stick to the tray and no matter how much you try you’ll never get it all off, and the “clumps”, if you could call them that, are not very easy to scoop out, either. And the stench is unreal, whole house reeked of cat pee after about a week, which was only about a third of the time they reckoned it would last for. Absolutely not worth your time.
