It’s a bit pricey for a little bag. But, the answers or peace of mind knowing BEFORE going to the vet makes it worth it.

I have four cats, including two seniors, so I’m always looking for ways to stay on top of their health. This product gave me peace of mind about their urinary health between vet visits. The booster pellets stayed white, which reassured me that there was no blood in their urine.

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!

Bought twice in three months. Never showed anything. Finally took my cat to the vet for blood test and found out my cat was in kidney failure! I was shocked and upset with myself thinking she was fine with the symptoms she was displaying bc I was depending on a vet developed substance for litter box. Expensive and Worthless!

I’ve been using The World’s Best Litter for about four years now, and I recently decided to try The World’s Best Boost Health Check. I have two cats, and since they’ve had urinary crystals in the past, I wanted to ensure everything was still okay. I purchased two bags—one for each litter box—and I was overall very happy with the product.I simply added a bag of the Boost to each box after fresh litter and sprinkled it evenly on top. There was more than enough in each bag, and I appreciated how careful placement made it easy to distribute. After using it, I didn’t notice any change in my cats' litter color, which is a good sign—they’re doing just fine.I’m really glad to have this option for monitoring their health, and I’ll definitely keep using it to stay proactive about their well-being.

There was barely enough to sprinkle across the top. It was not worth what I paid. I assume it worked because there was no color change.

Smaller package than I was expecting. Despite that, I wish I had something positive to say about how it works, because it would’ve saved me $107 for a urinalysis from the vet, but my cat REFUSED to go in her box when this litter was in there. I had to stir & cover and add a ton more litter to hide it. She still ran outside to go.

It does what it says excellent product
