Frequently Asked Questions

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.

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.
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.
Because Health Signal turns your litter box into something smarter. It doesn’t just hide odors, it absorbs faster, lasts longer, and gives you real-time health insights every time your cat pees, all throughout the day. One color, one signal, continuous clarity. No clumps, no dust, no stress. Just smarter care, built into your routine.
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.
