Smart collars get lumped together as "GPS trackers", but how they locate a cat and what they cost to run vary a lot. These are the five things to check before buying, alongside the actual spec ranges across the trackers we list.
This is the first fork in the road. If the cat might get outside, you want GPS; if the concern is finding it around the house, Bluetooth is realistic. Three of the six trackers we list use GPS. Settle this before comparing anything else.
These two move together. Subscription models here need charging every 2–15 days; subscription-free ones last a year to three. Whether you can live with the routine is what decides which side suits you.
Weight across the trackers we list runs 4–36 g, and the smaller the cat the more that matters. Water resistance counts if rain or spills are plausible — five of the six here have it, and it moves up the list if the cat goes outdoors at all.
It is a mounting difference, and which one a cat tolerates is individual. What matters more than the shape is the weight and whether it fits a breakaway collar. Among the trackers we list, the lightest options start around 4 g.
All six trackers we list have an app, but what the app does varies — some only show a location, while others add activity logging and geofence alerts.
