Today I fed Shinobi 1 medium sized adult mouse (instead of 3 hoppers) and although it took him a little longer to get down, he had no problems with it. That was about 3 hours ago and usually after I feed him he goes right back into his hide. Today, however, he hasnt gone back into his hide yet since I fed him. I'm thinking its probably just because he doesnt want to curl up with a larger prey item in his stomach. He's just hanging out in the front corner on the warm side of the tank. I guess I'll just have to keep an eye on him for now.
