I feed all my snakes live. Back when I had a couple snakes it might have been useful to feed F/T, but now it'd just be a major waste of money. I have some snakes that will turn their noses up at food for no apparent reason, and every time a snake does that, it means the food went to waste with F/T because I think re-heating F/T is kind of disgusting and unsafe. With live, I can put the rat back in a cage/habitat with food and water and it won't be "spoiled" - it'll be healthy and ready for next week.

I fed my snakes P/K for a while and feeding response went down. Live gives me the best feeding response among the babies and adults alike. Everyone gets watched until they kill their prey. When it comes to my spider male, who cannot do a head shot for the life of him, I will dangle it for him so he can get a head shot easier.
