This week, I tried pre-scenting the room with a live mouse (I could tell it worked--when I peeked in on Auryn, he was perched on his hide, waiting to strike). I "marinated" the F/T mouse in some used mouse bedding, and warmed it--but when I dangled the mouse for Auryn, no dice. He just wasn't striking--he flicked his tongue at it a few times, moved around, looked at it, but didn't go for it. After trying twice (warming it in between), I gave up and popped the live mouse into his tub. He struck the live one in seconds, coiled and swallowed.
It's so frustrating! He used to eat F/T weekly without issues, had a really good feeding response, and now he's only responding that way to live. The live mice at PetCo aren't really large enough for a decent meal (and these "snacks" are $2.50 a pop!). I'm going to try F/T again next week and hope for the best... if he doesn't decide to go for it soon, I'm going to have to find a live source!
