Up until about a year old I feed every 5 days. Hatchlings and juvies get a prey item about as large around as the snake's girthiest (is that a word?) section. Adults get a large wean/small small every day with girls getting ready to breed sometimes getting doubles. Adult males eat every 10 days or so. All snakes get 1 or 2 feedings off every 2 months or so. Either refusing because of shed or me skipping feeding them to give them a break. When you have a lot of snakes you get a feel for feeding. I hope this all makes sense!
