Ok, well, I tried today with a live feeder, just to make sure she'd eat at all. I used the tongs like someone had suggested, to acclamate Ari to them for when I try a f/t this weekend. She shied away at first, but after less than a minute, she suddenly turned and just attacked the little hopper! She even left blood on her aspen bedding. I was pretty surprised by her quick reaction to the mouse, but I guess it's good that she has such a good appetite. I'll try feeding her a f/t next weekend and let you guys know if it works. Thanks for all the advice.
