Here are some keys

1# Forget F/T try live, having your animal to eat is YOUR priority switching is completely secondary. Offer live Hopper Mouse.

2# Security and Warmth, I would suggest you to have this animal setup in a 6 quarts tub (No larger than that), have some aspen as substrate, a 6 inch plastic flower pot saucer as an hide and proper gradient temps.

3# NO HANDLING until the animal eats at least 5 times for you.
