About This Item

Details

  • The cat litter additive turns your kitty’s favorite litter into a health-monitoring system by detecting pH changes in her urine.
  • Easy-to-see indicator crystals change color when they detect irregularities in your cat’s urine pH, as such changes may indicate a potential urinary health condition.
  • There’s no need to switch to a new litter—just sprinkle the crystals evenly over your cat’s existing, fresh litter, completely covering the entire surface.
  • Use with every fresh litter box change or as needed after scooping—each 10-ounce bottle lasts up to 6 uses when used as directed in a 19x15 inch litter pan.
  • If you live in a multi-cat household, temporarily separate your furbabies so each one uses her own litter box treated with Health IQ crystals.

I was really looking forward to receiving this, but unfortunately it didn't work at all. The "beads" were an orange/clear color when they arrived, and never changed color in the litter. Followed all instructions and had fresh litter in the boxes. Wouldn't recommend this item.

you need to use quite a bit of it for it to work well, since every time they step in the box the litter gets moved around and it said it lasts several uses, I used it flr 2 boxes and didn't have enough to use it any more times, I'm sure it changes color but it's just not what I was expecting, we tried it though because other color litter gets expensive

It's hard to tell if it's even doing something. There will be one or 2 blue crystals but the rest of it's yellow and I don't know if that's just a reaction with the litter I use. Also it's hard to know if it's been 4 hours since my cat has peed to check the results.

you really need a lot more of it.

I used a whole bottle on one small box. I was only able to get two readings because the cat scratches and mixes it in.

uncertain

I'm not sure if it works because my cat avoids it. He will go elsewhere if he smells it in the box.

I bought this to try because it was a heck of a lot cheaper than a whole bag of color changing litter. You sprinkle this additive onto the top of the litter. You then pretty much have to stand over your cat to see anything because the cat will disperse it in the litter and you won’t be able to see any color change. The only way this may potentially work is if it’s the only thing in the litter box.

Wouldn't repurchase

If you bought 10 of these then maybe it would work, but I only bought 2. There is no way to get enough coverage to track results without several bottles. I love

If you bought 10 of these then maybe it would work, but I only bought 2. There is no way to get enough coverage to track results without several bottles. I love Arm & Hammer and swear by the Cloud Control litter, but I can't recommend this product.

Cats bury the evidence

I've tried this product a few times, thinking that I must be using it wrong. Every time I use it, the cats bury the crystals so that we can't see the results. Even

I've tried this product a few times, thinking that I must be using it wrong. Every time I use it, the cats bury the crystals so that we can't see the results. Even after losing my dignity and watching the cats pee, it was impossible to see the results. Won't use again.

To be able to see if there was a problem

I have multiple cats so couldn’t tell which one would have the issue
