I think you can do both. That's kinda the way I feed my snakes. If they get a large meal they eat roughly 14-17 days later. If they have a small meal they eat 7-10 days later. I mix up their prey sizes, prey types, and feeding frequencies. I'm fortunate that most of my critters will eat whatever & whenever I feed them. And if somebody does refuse a meal there's always another snake waiting for a meal or snack.![]()
