Each bun is an individual. The night we brought Thumper home he went from the carrier to his cage. The next morning my husband let him out. That very day he was coming up to each of us including the three girls.
He likes to be petted and rubbed just about anywhere. He's not crazy about his feet but sometimes when he is intent on chewing some cardboard we can touch them. He's a little sensitive about low on his side but when he's chilled out and I have been petting awhile he doesn't mind, even seems to enjoy it.
When he is being lazy he will stay laying down when we enter the room but when he's feeling more energetic he will come running to us.
