Published 20 June 2026
A compact, affordable activity and sleep tracker that clips to the collar and syncs to a tidy app, with no subscription. Good for basic step and rest tracking at a low price, though the health insights are shallower than the leaders.

Common questions
Is the PETKIT Fit good value?
Yes, as a cheap, simple activity and sleep tracker with no subscription and a long coin-cell battery, it covers the basics well. The trade-off is shallower health insights than dedicated leaders like PitPat or FitBark.
Is it suitable for cats?
Yes, it is very small and light, which suits cats and small dogs that might reject a bulkier device.
Does it need charging often?
No, it runs on a coin cell that lasts months, so charging is rarely a concern.
