Thanks for your response. I moved him because he previously was in the highest traffic room in the house: the computer and budgie room. There are two budgies in that room who are constantly making noise and we are always interacting with them. It's just a very noisy room combined with music. But regardless, he did used to eat in there, and there is a huge temp difference between that room and this room. I moved him to this room because he had already stopped eating and I wondered if putting him in a quieter place would encourage him more.
Also, he has only ever eaten F/T hoppers as long as I've had him. When I first purchased him from a breeder, he was eating 3 of those every 7 days. In the month or two before he stopped eating, it had gone down to 1-2 with no change in size of rat.
I wouldnt be surprised if he did go for a live rat because I usually have to dangle and move the rat in order to entice him.
OK, since I tried feeding yesterday, should I try again today? He was SO CLOSE yesterday, seriously. It was the first time he's shown any interest in all this time. When he yawned I thought for sure he'd eat...
