It clips to your cat’s collar and sends their live location straight to your phone — no Bluetooth or nearby device needed. Here’s the honest picture on size: it weighs 33 g, which sits well on a sturdy adult outdoor cat from around 4–5 kg, but would feel like too much on a kitten or a small indoor cat. A good rule of thumb is that a collar and everything on it should stay under about 1–2% of your cat’s body weight. If yours is fully grown and spends real time outside, they’ll barely notice it. If they’re petite, we’d gently suggest waiting — or asking us first. Always pair it with a quick-release safety collar.
