We made litter you can actually read.
TellTail started with a simple frustration: by the time something’s wrong with a cat, you’re usually the last to know. Cats hide everything. We wanted the litter box — the one place every cat visits every day — to quietly tell you a little more.
So we built a premium clumping litter infused with a food-grade pH indicator. It clumps hard, controls odor, and stays low-dust like any litter worth buying — and it changes color with your cat’s urine pH, so you can simply see it at a glance. No test strips, no apps, no fuss.
We’re a small, independent brand run by cat people who think pet products should be honest, useful, and calm — not gimmicky. TellTail is a litter first; the color is the bonus that earns its place on the shelf.
TellTail is a cat litter that changes color in response to your cat’s urine pH. It is not a medical or diagnostic device and does not diagnose any condition. If anything about your cat’s health concerns you, talk to your veterinarian.
