Review: Simple to use, reassuring, and very practical for routine monitoring - I started using this litter additive as an extra way to keep an eye on my cats’ litter box habits, and I’ve been very pleased with how simple and practical it is. It’s easy to use—there’s no need to change litter, as it can be sprinkled directly on top of your regular litter. It blended in right away. Since I use a clumping litter, I can’t comment on clumping performance, but I didn’t notice any increase in dust, which I appreciate. The results are quick and easy to read. It honestly feels a bit like a small chemistry experiment, which brings out the scientist in me—in a good way. I like that it focuses on detecting changes related to blood rather than just general litter conditions, which feels more meaningful for routine monitoring. The product is designed to last for an extended period, though I personally deep clean the litter box weekly, so I haven’t tested it beyond that timeframe. Even with weekly maintenance, it still feels cost-effective and provides extra peace of mind. Overall, this is a simple, non-invasive, and easy-to-use addition to a regular litter box routine. A practical option for cat parents who want an extra layer of awareness without changing their current setup.
Review: Great for monitoring cat bladder health - I found these after my vet had suggested a urine test for my cat as part of a regular check-up. I didn't want her to have to go through the procedure (and pay for it) if it wasn't needed so got this instead. The package is smaller than I had thought but there's enough for more than one litter box in my opinion. The point of it is to detect abnormalities in urine and I think it does that well. It's very lightweight, doesn't really have a smell. It clumped together with the litter that was in the box so I believe it's somewhat clumping. I went ahead and bought three bags so I can do checks every now and then. You just never know with cats.

### ⭐⭐⭐⭐⭐ Nice to have on hand
*by B***V on January 31, 2026*

Great to have on hand when your kitty starts using the litter box too frequently. Pebbles are larger and white than the litter, so they're easy to keep your eye on them.
