Has anyone ever noticed this? I primarily feed f/t to my snakes, but I have one that will only eat live. So at times the live one I have bought a food item wont be taken by my live feeder. I end up giving it to one of my other snakes. I've noticed ever since I started doing this, that one of the snakes that usually fed on f/t is now starting to refuse f/t meals. So I have to ask anyone else ever notice this with theirs?
