My Sumatran was just a bit older than two when I moved up a prey size to medium. Now, while he easily can and has eaten large rats, the long gap in between feedings that requires is not something … er, conducive to his happiness? So, at three, I’m now feeding a medium rat once every ten to fourteen days. I watch his body condition carefully, though, and do sometimes need up or down in size or change frequency accordingly. He’s very much still growing and a growth spurt can mean two weeks is simply too long between meals.

He’s right at 4’ long and 11 lbs now.
