A very pretty normal. You never know, could have a hidden gene in there somewhere. Of course, the only way to prove that out is breeding. He is such a cutie! I love the little ones.
I would give him a week before feeding too. Right now he's just checking things out and making sure his new home is safe. You don't want him finding a mouse, and freaking out because he thinks it's the mouse's home. Lol.
Good luck with him and Congrats!
