We fed Jade, our yearling, live for a while, but it's just too intense for her. We've since then switched her back to FT and she will just eat it off the ground. We've had some very near misses (our face, her mouth) when feeding live. She just got so worked up we decided that we don't want a full grown animal doing that, so we went back to FT.
I don't really care how we feed them, honestly, FT, live, PK. It doesnt make a difference to me. But if I could, I would love to just toss in a FT rat for everyone and call it good. But not all snakes will just eat a FT off the ground, they have to be enticed by the 'zombie dance' and when you get up in numbers, it takes a lot of time to dance for each snake.That's why we do live, plus a refusal can go back into the bin.
