British Cat with an Usual Habit

This is a true story about a cat that regularly rides the bus by himself. Here is the link to the full article.

I wonder if he is following a pattern that his owner traveled?

Maybe his human died and the cat is following the human spirit around?

Is it a human spirit walking around in a cat body?

Is it a familiar on a specific mission?

Was the cat trained by someone to do this for them?

Does the cat have some kind of medical condition like arthritis and this is a solution to walking the entire distance?

Is he visiting someone or doing something on a regular basis once he gets off the bus?

Is he avoiding another cat's territory?

Is his territory split somehow?

Is there some kind of barrier like a busy highway or waterway dividing his territory and this is how he gets around the obstacle?

Is there any doubt I am supposed to be an animal behaviorist? :)
Cool huh?!
