Boosters™ Health Check-in™ | Cat Litter Additive for Health Monitoring | UTI Monitoring and Detection with Color Changing Indicator | Vet Approved | Single Packet, 12g

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 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.

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

Waste of money. Most litter has deodorizers, & apparently thos product does not work with those litters. On top of that it is a real small bag. Not worth the price. I wish I could get my money back for the used bag but- I could only return one. They should have stated that it doesn't work with CERTAIN litters, I had to research to figure out if it was really working.

There is no smell or dust with this product. While I love the idea of using this to detect any urine issues with the cats I have to say the bag is really small, think snack size if buying chips. Bag is filled half way just like your potato chip bags. I think value for the money is a little low but I guess peace of mind may be worth it. It would be worth about $5 for this size bag and then it would be a good value. I would have given it 5 stars except for the small amount you get. I can't speak as to the effectiveness as of yet. I do love Worlds Best Litter though!

Product works as intended but is literally maybe 1/8 cup worth of product to try and sprinkle over where your cat might go to the bathroom and be enough to make a difference and show up if something is wrong. Just not enough in my opinion to do really thorough testing. Be sure to sprinkle this in the spot where your cat most uses the litter box

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.

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.

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.

Good item to add to the FIC management toolbox.

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.
