AI Review Summary
The Arm & Hammer Health IQ Cat Litter Additive receives varied feedback regarding its core functionality. Many users report that the product effectively monitors health by changing colour, providing early detection of urinary issues and offering reassurance. However, a significant number of users did not observe any colour changes, or found the changes subtle, inconsistent, or less thorough than alternative products. Regarding odour control, most reviews indicate the additive effectively neutralizes unpleasant smells, significantly reducing litter box odours. Conversely, a few users noted no improvement in odour control or reported persistent odours. The product is generally considered affordable and budget-friendly, though some users find it can become expensive due to the quantity required, especially for larger litter boxes. Cats typically adapt well to the additive and show no aversion to its presence. Users appreciate the ease of use, describing it as simple to sprinkle or mix into existing litter. The additive also contributes to a sense of peace of mind regarding feline health. There is mixed feedback on its impact on litter clumping, with some noting improvement and others reporting a reduction in clumping effectiveness.
Litter Box Additive
I thought I would give this product a try as the colour changing litters to help determine your cat's urinary health are so costly. This was modestly priced and did the job well. The only downfall is I have a Bengal cat who is quite long so I have a very large litter box and I have to use the entire container to adequately cover the litter for it to work properly.

Freshness & Comfort for Kitty
I don’t have cats myself, but my close friend on the farm does, and I gave this to her to try. She swears by it now. She said it helped keep her litter box smelling fresh way longer, and she felt better knowing it had a health-monitoring aspect to it too. I helped her pour it in, and it blended so well with the litter—no clumps, no weird smell, just freshness. The cats had no issues adjusting either. If you're someone who wants to feel more confident about your pet’s health without changing your whole routine, this is a good one to try.
I would not trust
I find this product to be something I would advise against. As a cat owner, you should be able to tell if your cat is in distress or may have urinary concerns without having to sprinkle some chemical into their litter box. Also, if you have multiple cats this product will not work esp when you have to wait 4 hours. Please just give your cats lots of fresh water and if you notice anything unusual - take them to the vet.

It wasn’t anything special
This is supposed to be a health-monitoring additive you sprinkle into your regular litter, kind of like Pretty Litter. I really wanted to like it, but honestly? I didn’t notice anything. No color change, no obvious signs …nothing that made me feel like it was doing what it promised. Unless you’re supposed to dump in half the bottle at once (which would get expensive fast), it just kind of blended in and did… nothing. If my cat had something going on, I definitely wouldn’t have known from this. It felt more like a marketing idea than something that actually works. As a regular deodorizer or additive, it’s fine. But as a health tracker? Not impressed.
Not easy to see any results
It doesn't really work as far as I could see anyways..i didnt see any changes...it wasnt really worth the money in my opinion anyways
Litter Box Oracle
This additive transforms your cat's litter into a health-monitoring system. The color-changing crystals detect pH changes in urine, potentially indicating urinary health issues. It's easy to use—just sprinkle it over your existing litter. While it doesn't control odors, it provides peace of mind by alerting you to possible health concerns. Some users find the color changes subtle, but it's a helpful tool for early detection. Affordable and compatible with most litters, it's a valuable addition to your cat care routine.
Effective, could be a little stronger
This is an overall great product. We have 2 cats and this does the trick! We just wish it was a little more intense / longer lasting. Still a regular for us.

Great Help for Kitty
My cat has been more susceptible to urinary tract infections and this product is so helpful for early detection. It's hard to tell that she's getting an infection because cats don't really make a big deal of things unless it's really bothering them. This product helps me to get her to the vet for medication before it becomes a major issue for her.
