It's a bit expensive, but you don't need to use a whole lot of the granules for a result. I like to have Health IQ on hand to spot check our cats' health, especially since it warns us of pH issues before they get too severe.

This is extremely inexpensive. The packaging is nice, the top is easy to remove on and off, as far as effectiveness goes there are other products on the market that are much easier to read/understand. Doesn’t do much for odor, it does tell you if your cats PH is off, but it’s very hard to tell the color change. Is eco-friendly, but wouldn’t purchase again.

It doesn't necessarily control any odor going on in the litter box, but it does change color. At first when I used this product I thought it wasn't going to change colors based on my cat's health, so I'm shocked! This litter also doesn't cause any harm whatsoever to my kittens or cats! The bottle is just like opening those crystals for laundry lol. It's definitely worth the money & makes things interesting & you'll learn something important about what's going on with your car or kittens health wise.
