I feed f/t and I feed in the enclosure. I either thaw my rats out on the counter (takes a couple hours) or I put them in the fridge and let them thaw over night. I warm them in hot water for 10 min and they're good to go! I try not to handle the rats with my bare hands bc I'm HIGHLY allergic to them! They stay in the baggie all through the thawing and heating process and then I handle them with tongs. With one of my snakes I don't even have to do a zombie rat dance...as soon as he smells it, it's over! My newest little guy still needs a little convincing, LOL, so the rat does a little dance all over the place!
