well done thats good your blood is eating, in general they are great feeders and always eager to eat so be careful not to over feed, I have seen some really overweight bloods even though they are a very thick set species.
And as bruce said dont get between your blood and a rat they hit very hard I made the mistake of not paying attention when opening the lid to a feeding box with my big female and she hit me like a ton of bricks after downing a jumbo rat ....she was still hungry and I had a lapse in concentration watching a boxing match on tv whilst opening the lid and bam this was the result ...
sometimes reminders are not the gentle ones you hope for lol
