Hi,I will tell you my method that works for me ok?I take the mouse from the freezer and put it in a glass with warm water(about as worm as you can get from the sink...and then i leave it for like 5 minutes then I change the water again and wait another 5 minutes...then i take the snake from his cage and put it in a separate box...meanwhile i bun the mouse near the light bulb to heat it up so the snake will think it's alive...I leave it near the light bulb for like 3-5 minutes the i hold the mouse by it's tail and wiggle it in front of my snake left right...when I see that it follows it I hold the mouse in place and just wiggle it...and he takes it...My mouse are fuzzyes so they are pretty small...what size are you feeding yours?hope this helps...
