I can't try anything new now since mine looks like she's going into shed. I hope so; she never lost her eye caps from the last shed. I wanna see those beautiful baby blacks. -lol- But anyway, she's been eating medium rats because thats what the owner of my local specialty reptile store suggested she eat when I brought her in. Personally, I think they're huge. I would say a small rat, but not a medium. I'm afraid to feed her something that large so often. He seems to think there's nothing wrong with how I feed her. He's never said so in so many words, but I've explained what I do and he's never told me anything except give her larger prey.
