What a difference in quality!
What a difference with CatCheck! I noticed the improvement right away. The cat litter feels much more premium, the litter box stays fresh for longer, and whenever I have a question, I receive a quick and personal response. It's not just the product that's better, the customer service is too!

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
I was skeptical at first.
I wasn’t sure it would work, but it works perfectly! The color changes are still clearly visible.
- 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?
Yes, absolutely! Health Signal is made from silica gel, a mineral-based material that is also commonly used in products such as food packaging and toothpaste. The crystals contain tiny pores that rapidly absorb urine and effectively trap unpleasant odors, keeping the litter box cleaner and fresher for longer. No added fragrances, no clouds of dust, just clean, hygienic care for your cat with peace of mind.
How much litter is in one bag, and how long does it last?
One bag of Health Signal contains 4.5 liters (2.7 kg) of smart cat litter. We prefer to measure in bags rather than liters, as this gives you a clearer idea of how much litter you'll actually need. Our specially designed silica crystals are much lighter than traditional cat litter and offer exceptional absorbency.
The crystals absorb urine and trap unpleasant odors without forming clumps. Thanks to the antibacterial formula, the litter box also stays hygienic and fresh.
This means there's no need to scoop out urine clumps every day. Simply remove solid waste and give the litter a quick stir. Less scooping, less hassle, and more quality time with your cat!
On average, one bag lasts an entire month for one cat. The exact lifespan may vary depending on your cat's size and how frequently they urinate.
Why should I switch from my current cat litter?
Because Health Signal offers so much more than traditional cat litter: less maintenance, faster absorption, long-lasting freshness, and real-time health insights every time your cat urinates. No clumps, virtually no dust, and greater peace of mind. Make the switch today and experience the difference in convenience and confidence for yourself!
How does it work with multiple cats?
Health Signal also works great in multi-cat households! When you first start using Health Signal, you'll learn what color the crystals normally turn after your cats urinate. This is usually yellow to olive green. As long as you don't notice any unusual color changes, you can continue using the litter box as usual.
If you notice an unusual color that persists for more than 48 hours, you can temporarily provide separate litter boxes or keep a closer eye on your cats. This makes it easier to identify which cat may need extra attention or a check-up with the veterinarian.
Wat betekenen de verschillende kleuren van Health Signal?
Katten laten vaak pas laat merken dat er iets mis is. Health Signal helpt je mogelijke gezondheidsproblemen, zoals blaasontsteking, blaasgruis of blaasstenen, eerder op te merken door kleurveranderingen in de kristallen.
- Geel tot olijfgroen: Normale kleurreactie.
- Oranje: Zure urine, mogelijk verhoogd risico op bepaalde blaasstenen.
- Blauw of donkergroen: Alkalische urine, mogelijk verhoogd risico op struvietstenen.
Vervang bij verkleuring eerst de volledige vulling door een nieuwe zak. Blijft de afwijkende kleur daarna gedurende 48 uur terugkomen? Raadpleeg dan je dierenarts.
Zo houd je iedere dag ongemerkt een extra oogje op de gezondheid van je kat.
Kan ik Health Signal gebruiken in een automatische kattenbak?
Ja! Health Signal is geschikt voor de meeste automatische kattenbakken.
De kristallen absorberen de urine, terwijl de automatische kattenbak de ontlasting verwijdert.
Stel de reinigingscyclus bij voorkeur in op 7 tot 14 minuten na gebruik. Zo krijgen de kristallen voldoende tijd om urine op te nemen en kun je eventuele kleurveranderingen bekijken.
Kan ik Health Signal gebruiken als ik meerdere katten heb?
Jazeker! Reken gemiddeld op één zak per kat per maand.
Heb je bijvoorbeeld twee katten die één gemiddelde kattenbak delen? Dan gebruik je één volledige zak tegelijk en vervang je die na ongeveer twee weken. Zo heb je in totaal twee zakken per maand nodig.
Bij een extra grote kattenbak kan meer vulling tegelijkertijd nodig zijn om voldoende laagdikte te bereiken.
Zie je een afwijkende kleur? Houd dan in de gaten welke kat de bak gebruikt of gebruik tijdelijk aparte kattenbakken gebruiken om te achterhalen bij welke kat de verandering optreedt.
