No more litter trails
“She used to track litter all over the place. This one stays where it belongs.”
- Sophie
Still smells fresh with two cats
“I used to notice the smell as soon as I walked in. Not anymore. And I don’t have to clean as often either.”
- Mark
Works just fine with my robot box
“I wasn’t sure it’d be compatible, but it works great. The color change still shows up clearly.”
- Lisa
Total upgrade from regular litter
“I used to buy whatever was on sale. This is just... smarter. You can really tell.”
- Emma
I wouldn't have noticed otherwise
My cat seemed totally fine, but the litter suddenly changed color. Turned out it was a mild UTI. So glad I caught it early.
- Sarah
Caught it just in time
My vet said if I'd waited, it could've gotten worse. The litter's color change is the only reason I noticed.

Frequently Asked Questions
Is this safe for my cat?
Health Signal is made from silica gel, a mineral-like material also found in products like food packaging and toothpaste. It's completely safe for cats, even if they lick it. The granules contain tiny pores that instantly absorb urine and lock in odors, keeping the litter box cleaner for longer, without clumping, or smelling. No perfumes, no dust clouds, no worries, just smart, hygienic cat care.
What do the colors in the litter box mean?
After each pee, the crystals usually show one main color in one spot. Yellow to olive green? All good. If you see red, orange or blue-green that doesn't fade within 48 hours, it's smart to check in with your vet. No stress, just a clever way to spot changes early.
Can I use this with an automatic litter box?
Yes, and surprisingly well. While most non-clumping litters don't work with automatic boxes, Health Signal does. Solid waste is still removed by the system, and the urine is absorbed deep into the crystals. The surface stays dry, odor-free, and color changes remain visible. So you still get your health insight, even with a self-cleaning setup.
What if my cat doesn't use it right away?
Some cats need a little time to adjust, and that's completely normal. To help with the transition, start by mixing Health Signal with their current litter and gradually increase the amount. The formula is scent-free, low-dust, and soft on paws, so most cats feel comfortable quickly. With a bit of patience, almost all cats make the switch with ease.
How does it work with multiple cats?
Health Signal works perfectly for households with multiple cats. We recommend using one box per cat for the best health monitoring results.

Early signals health problems
Our color-changing crystals alert you to changes in your cat's urine that may indicate an underlying health problem. From urinary infections to stress-related issues or even blood in the urine, Health Signal helps you catch it early. No guessing, just daily peace of mind.
Less smell, less shoveling, and low-maintenance
Health Signal absorbs urine instantly and locks in odors without using perfume. No clumps, no sticky mess, no unpleasant smell when you open the box. Whether you scoop by hand or use an automatic litter box, it stays fresh and hygienic with minimal effort.
Stays neatly in the bin,
– just a clean home
Our low-dust granules don't stick to paws or fur and stay where they belong: in the litter box. That means no trail of litter on your floor and no clouds of dust. Ideal for sensitive cats - and for people who like a clean home.

“Katten laten pijn vaak nauwelijks zien. Juist daarom vind ik CatCheck zo waardevol. De kristallen kunnen verkleuren bij opvallende veranderingen in de urine. Zo krijg je thuis een extra signaal om op te letten. Soms begint goede zorg met iets kleins.”

“De kattenbak kan meer vertellen dan je denkt. CatCheck helpt je veranderingen in de urine op te merken, terwijl de kristallen ook nare geurtjes tegengaan. Zo combineer je aandacht voor de gezondheid van je kat met een fris huis.”

“Een frisse kattenbak hoeft geen dagelijks gedoe te zijn. CatCheck absorbeert urine, houdt vervelende geurtjes onder controle en is vrijwel stofvrij. Even de ontlasting verwijderen en de kristallen doorroeren. Dat maakt de verzorging makkelijker voor jou en prettiger voor je kat.”
