Personally I feed Loki 2 small mice a week. He just kept seeming like he was hungry with only one, so I bumped it up. After the second mouse, he isn't looking for anything else to eat. But he's also at about 23 inches now, don't know how much he weights don't have a scale yet. Just thought I'd throw that out there.
I feed both Live & F/T now. Just whatever I have on hand or the money for. I keep F/T for when I don't have the money to get some Live(stunned). Loki will eat both. (thankfully)
