Health Signal is designed to reduce waste and use resources more efficiently. One bag lasts an average of one month for a single cat. Because our litter lasts much longer than traditional cat litter, you use less material and throw away less. This saves both raw materials and waste.Plus, Health Signal is ultra-lightweight (2.7 kg), which means lower CO₂ emissions during transport. And we don’t use perfumes or harmful chemicals, better for your home’s air quality and for the environment as a whole.
At Health Signal, we stop odors at the source. As soon as your cat urinates, our crystals rapidly absorb the moisture into millions of microscopic pores. This keeps the litter box dry and prevents bacteria, the real cause of bad smells, from spreading. The odor molecules are locked deep inside the crystals, giving you long-lasting freshness. No perfumes, no masking, just pure odor control. Some cats, like larger breeds or frequent drinkers, may pee more. In that case, it’s smart to replace the litter a little sooner or add some extra to keep your odor control at its best.

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.
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.
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.

“She used to track litter all over the place. This one stays where it belongs.”
Cats are masters at hiding pain and symptoms. That’s why Health Signal is designed to help you catch subtle changes in your cat’s urine – directly from the litter box. When something’s off, the crystals change color as a gentle warning sign.
Veterinarians recommend Health Signal as a smart, supportive tool in your daily care routine. No stress, no hassle – just an extra layer of love and health monitoring for your feline friend.
