So, transitioning to Reptilinks is proving to be more challenging than I thought. The first time I fed him a Reptilink, I just scented the link by rubbing it on a hopper. He took it no problem. The second time I tried not scenting it. When that didn't work, I scented it, as before, and he took it just fine. Last night, I tried lightly scenting half of the link. When that didn't work, I scented it as before. When that didn't work, I paired it with a mouse tail. When that didn't work, I slathered it in mouse entrails. That worked.
However, I don't want to keep buying mice in order to feed Reptilinks. That's not efficient. I could just buy one mouse, puree it and coat all my Reptilinks at one time, but, before I resort to that, I think I'll try simply waiting until he's positively ravenous before feeding him.
