Lewy gave me the great advice of taking Saphy out of her viv and feeding her on a mat or something, I use a salad draw out of a fridge that id took out to get more beer in :D , I wiggle the mouse infront of her with some tongs and she strikes everytime and eats it there and then with no fuss, also you get the added bonus of watching your corn eat, which I must say is one of the best things Iv seen ever lol.
