how did you acquire said squirrel?
Breeders sell them.
If you get them when they're really young, they bond with their owner, and sees you as some kind of safe tree or something.
When he gets spooked, he runs to where I am, but he usually doesn't get too far away from me.
He's like a little kid like that. When he starts to wander away from me, he pauses, like he knows he's getting too far away, and he'll run back for a second, just to make sure he still knows where I am. Then he'll run back to where he was exploring.
In the wild, they live about two years.
In captivity, where they get all the nutrients they need, and don't have owls eating them, they can live up to about 15 years.
