Yes, Thor's absolute favorite toy in the world is a dirty sock. He hoards them like some kind of stalker.

He likes his tiny squeaky tennis balls too, but he's not really into his other toys. I've tried out some plush squeaky toys on him in the pet store because
I think they are super-cute, but he always runs away from them! I really think Thor has a chicken somewhere in his family tree.
I ordered the Hide-A-Squirrel recently because it seems to be really popular, and I have high hopes that Thor will take to it. He would definitely love a Hide-A-Pigeon.

I love that he hates those birds as much as I do. I always let him chase them in the park.
