at the recommendation of a good friend, Brian from Chicago Reptile House, I feed my little guys (<600 grams) every 3 days. That's my schedule, that doesn't meant they follow it. I am very consious of who likes to eat often and who doesn't. I have one Mojave that will eat every two days if I put it in front of him. He has healthy stools, too, so he digestions just works a little faster. But then I have some that will only eat every 8-10 days. So, it all evens out. I'm on day 4 right now and I'm starting my feeding today.
I also breed my own rats, so I feed live. Even though I keep my rats in the same room, my guys and gals are real god about feeding time. Quick, successful kills everytime, right away.
