Review on Ultra Cat Health Monthly 🐱 Monitor Crystal: Ensuring Optimal Feline Wellness, 16oz by Tara Clark

Love it - inexpensive and easy to use. If your cat is anything like my cat, changing the litter will scare her and she will avoid the litter box for a while. When my cat finally used the letter it was hard to tell if that was normal or not because the sand that was on the litter mixed with the litter after the kitten covered up his business. I didn't see any blue or green, so everything is ok? It's just very difficult to say. I won't buy this again. My cat will only continue to use this crystal litter if and only if another litter box in the house is not scooped out within two days.
