I don't believe so? His enclosure isn't very small. I fed him on the complete opposite side of where the blood trails to. I feed him frozen hoppers. Unless he got it on himself and it dripped off...

But even so, there wasn't a lot of blood but it still seemed like too much to come from the feeder.

I didn't watch him eat, but I know he usually eats it right where I drop it and doesn't leave that spot until he's finished. Which makes it strange that there's drops trailing across the enclosure.
