It's NOT supposed to happen in U.k. Any Reptile you but in England, should be on f/t food already. I think it is actually Illegal to feed live prey because it's supposed to cause stress to the prey item. (It's gonna die, so I don't see that stress will be a problem anyway.) Like I said, all reptiles sold in this country will already be on f/t.
