Six months after my move I decided to let the cat out finally and he disappeared. Two days later I get a call from the old landlady that the cat had turned up there, almost 2 miles away. This is across a pretty busy city with some majorly busy streets.
I still have no idea how he could have done that. I read someplace they have an innate sense of time and a memory for the position of the sun and that's how they navigate.
