I personally feed all my younger snakes twice a week. They all seem to be doing great. All the food that I give them is small, some people would say it's way to small. I feel that more frequent smaller meals are much better for them.
I have also noticed that all my snakes seem to be more active a lot faster when feed smaller meals more frequently. They rarely have the period of time where they just sit there and digest. All are usually active by the next day. Also you can rarely ever tell that the snakes just ate, there isn't a lump in them.
I dot know what other people do but this seems to work great. As a bonus they all seem to put weight on a lot better with this method, and it is lean weight not fat.
