It is the best - by far. No dust, no smell and it lasts.

My cat has been diagnosed with FIC and I am monitoring her urine for blood as there is no cure only treatment for this condition. The crystals turn dark blue or green when there is the presence of blood or other issues (glucose) Please note that you sprinkle the whole package over the surface of your cat's litter. You do not put one or two crystals on top of the urine. That's not how it works.

We adopted a new cat and I noticed she was in the litter box more than I thought would be normal. She did not have any other symptoms so instead of a traumatic vet trip I figured I’d give this a try for an day and continue to monitor her for any other symptoms before we went to the vet. She did not mind this being mixed in the litter, it never changed color (it does naturally after being in the litter for a long time, so don’t panic). I kept monitoring her otherwise and determined she was just very curious about the litter box was and was totally healthy. (Yes, we did make a vet trip to be sure).

I bought 4 packages. My cat HAS UTI ! It did not show up at all with 4 bags !!!! What a waste of money. Plus if your cat is ill. This does not show it. That's dangerous. Take your cat to the Vet. it is safer. More expensive. But your cats health matters.

I use this brand’s litter and really like it for keeping odors down. I saw this and wanted to check my kitties urine for any signs of a problem. It hasn’t changed to one of the color indicators so I assume it’s working, and the girls have no UTI issues. I’m going to buy this again to use if I suspect a bladder issue.
