Thank you for the replies everyone!

I am going to wait a week before trying again. I'll try not handling him before feeding him too. I want him to eat, but I also want him to become "tame" so he's not afraid when i take him out, but getting him to eat is obviously most important!

If I try feeding him in his enclosure next time, how should i do it? He is always in his hide, should i wiggle the mouse in front of his hide? Should i just drop it in front of his hide?

You can see the pretty little guy in my avatar!

Thanks!
