Well he's a 2010 and is about 850 grams, so I guess it could be a breeding thing. But I think he started refusing around August-September so I thought that might be too early for him to start refusing because of wanting to breed.

I don't remember how the last feeding went, other than he ate. lol. I panic pretty easily so if something was off or I felt that there was a problem with the feeding or him, I'd definitely remember that. I warm my rats straight in water and he's always eaten them that way. Should I try another way of warming it?

If I do decide to try live and he refuses that, I'll give it to one of my others. I don't have the heart to kill it myself and I can't keep a rat for however long it takes him to start eating again. This might be a silly question, but if I do give it to one of the others, will they start refusing f/t and only want live?
