I sure know the feeling and been going through the same thing. Mines almost to the point he seems to be taunting me lol. He was eating small rats fine before but I'm going to start this next feeding day playing around with different size prey items. I have a ton of f/t fuzzy rats and I'm going to try and see if one of those may get him going again and if that doesn't work the next weekend I'll run up to the expo and pick up some weanlings and try those. Hopefully maybe get him going again and work him back up to the small rats.
My daughters little Mohave girl when we first got her refused the first time but seemed VERY interested. Next feeding I tried a different size larger fuzzy rat and she slammed it. Been eating great ever since with just a change in prey size.
