GPSing Your Cat

Author Caroline Paul's cat disappeared for five weeks before returning home. Wondering where he went she fixed him up with GPS and mapped his wonderings.

 The story and process are documented in Lost Cat: A True Story of Love, Desperation, and GPS Technology. The map above shows 10 hours of the cat's wanderings through part of San Francisco. He prefers certain nearby houses, but does get around and crosses many streets. He appears to have little interest in that water tower-like structure at the top of the image.

Upon further digging, I found this map from the book on the Lost Cat website showing the neighborhoods as seen by their cat.
