One of mine does this. I think it's completely food related. It got so bad, I couldn't even get the rat in the cage, he'd start lunging for it before I even got it near him. The last two feedings, he ate hanging off the side of his enclosure. I'll be moving him to a tub soon because it's become hard to take care regular husbandry while trying not to get bit. I have him on a 5 day eating schedule now to see if it helps any.

After he has eaten, he's been just fine. Or after he bites me, he realizes it wasn't feeding time. I'd like any other tips, I'm open to try anything else.
