How to map your cat's territory (and see who it overlaps with)

Cats don't wander randomly. Given a few days of location history, a clear shape appears: a core area around home plus corridors out to favourite spots. That shape is the territory.

What a cat territory looks like on a map

Most house cats keep a small core area they use daily and a wider range they visit less often. Neutered indoor-outdoor cats usually stay closer to home than intact cats, and city cats generally use less ground than cats in the countryside.

Two ways to get a territory outline

Draw it by hand. Open the map, tap the corners of the area you know your cat uses and close the shape. Useful before you own a tracker.
Build it from GPS points. With a tracker connected, the outline is generated from recorded positions and updates as new data arrives.

When two territories overlap

Overlap means the cats share ground — a shared hedge, a warm garage roof, the same feeding human. Catlantic shows neighbouring cats whose territory touches yours, so you can send the other owner a friend request and compare notes.

What to do with the shape

Spot roads at the edge of the range and where to add deterrents.
See if the territory shrinks — a common early sign of pain or illness.
Introduce yourself to the neighbours your cat already visits.
