Bleating Goat has brought up a subject that is often referred to but never discussed in any significant detail.

Over the years I have found that snakes often do best when fed at the rate they chose, not some scheduled interval rigidly adhered to by the keeper.

Some species of boids will readily eat every 4 or so days when they are young. Some young colubrids will eat more frequently. A lot of my colubrids will eat like the blazes for their first 14 to 16 months, then taper down - on their own.

If you keep accurate records, you can see the feeding patterns and plan accordingly. My antaresia males eat like clockwork from February to September - bulking up for the mating season. Around late August they taper down, taking a medium sized meal every two weeks or so until they stop altogether.

My aspidities follow a similar pattern - wherein the males "power feed" themselves from July through October, then will eat once every three weeks or so until mid January.

During the heavy feeding period, my large black headed male and my woma males will eat large meals every 6 to 8 days.

Young colubrids, notably clelia and drymarchon, are constantly hungry. However, once sated, they will stop. It is not uncommon to have young drys eat several small items, poop two days later and be on the prowl for more food the following day.

Now, there are a lot of species I don't keep, and these guidelines may not apply. It seems to me that if given the opportunity, most snakes will chose a schedule that works right for them.
