He typically eats small rats. the worst thing about this phase is the waste of food animals. I have no great affection for rats, but I'd prefer not to waste their lives. And none of my other snakes are large enough for small rats.
I have no idea what his weight is now. I stopped weighing him some time ago, there just seemed to be little point as he's always done well and I don't breed. He doesn't appear to have lost any weight.
Like I said, I'm not worried at all as this behavior seems normal. Just need to wait it out. Do the females do this also?
