Feeding Experts help!?

You have a few options. Like others have mentioned look for mice in your area on line. I believe there are places that specialize in shipping feeders (not live) and use dry ice to pack them. If you are in Northern MN, have you looked at the Brainerd or Duluth areas? I know you'd still have a drive, but it would be closer than the cities. Maybe you could call Twin Cities Reptiles and work out a shipping deal with them.

I am also relatively new to this but want to help like others have helped me. I was given advice to thaw the mouse over the top of the cage for close to a day. It's a slow process, and then when the rodent is at room temp, you can do a quick heat in warm, not super hot water and/or use a hair dryer and heat it up just before you feed.

I usually wrap the rat/mouse in a paper towel and having done this several times, I drop the paper towel (same one I always use) in an hour before I feed and blow it toward the area of the snake. I usually see a head pop out soon after and her tongue starts flicking. Our snake was a live only feeder when we got her and it only took 1 refusal and a week long wait and she hit the FT'd mouse and we've been doing fine since.

Does your snake show any interest in the prey? You may have to wait a week or 2 and try. I don't think anything is critical yet.

Don't stress out and keep trying and disturbing the snake. Let it settle a week and try the paper towel trick once you get the proper sized rodent.
