So I've had a problem, mainly with my albino male, to where he will seem very hungry and grab the rat right away and coil it (aggressively), but 30 minutes later the rat is still sitting in his cage and he doesn't seem interested. At that point, I'll reheat the rat, and he grabs it right away again without hesitation, only to find it still there 30 minutes later. It seems like he just can't figure out how to actually consume the rat and loses interest. I've left it longer too without success, so I generally try a few times until he eats it (or doesn't). He has fed relatively consistently for me, sometimes it takes once, others it takes several times.

Maybe he just wants a smaller meal? I'll weigh the rat and him and see if its within range.
What would cause him to take it and not eat it?

Cool side has been 78-82, warm spot 90-94, humidity is in 60's.
