Thank you soooo much for posting this!
I just tried feeding my BP earlier in the evening again and he still didn't eat. This is the third time he has refused food since May 18th. He was on a 10 day schedule before that and fed well both times for me.
I am going to try some of the things that you have listed hereI did find it interesting that you mentioned the color and sex of the rats. He has started refusing food ever since I bought male white rats. Before that he had eaten 2 times for me (I have only had him since 4/27/09 and he shed a week later) and both times the rats happen to be white with black spots and were females! I had know idea that color and sex may have something to do with it!!!
One question I still have is, since he has been refusing food, how many days should I wait between attempting to feed him again? I don't want to stress him out even more by offering food to often but don't want to wait too long either.
