I seem to always have trouble getting the mouse to the right temp for my Banana Ball. He's interested, comes out, sniffs it, and then after 20 seconds or so, goes back into his hide. He's never been a picky eater but I feel like the mouse temp isn't quite right. I have been using a hair dryer, but roughly how long should I heat up the mouse w/ the hair dryer? Is there a more efficient way that people recommend?
