Honestly I don't know the age. I was new to this and never asked but he was on hoppers when I got him at the show.
It's a banana ball. The mouse almost exploded which should have been the first sign. Hes been eating live feeders. I try the f/t and if fails ( has every single time) I get a live one the next day.
He comes right out when he sees the f/t, smells it, and looks repulsed. He turns around and refuses it.
