I don't know how often CM feeds, but in the wild I imagine that an adult retic wouldn't eat more than once a month or even longer in between. Even my smaller snakes only get fed every 2-3 weeks....I've got no weekly feeders except my false water cobras and my snail eaters...the former because they have extremely fast metabolisms and so get fed every 9 days or so and the latter because they eat snails only. They get fed more frequently due to their nutritional requirements. Corns, amazons, green trees, and all venomous are fed every 2-3 weeks once they get older. Babies get fed every 7-10 days depending upon the species and prey size. I found if I fed my Amazon babies every week they didn't eat. Every 10-14, they ate every time. Most boas and pythons have slower metabolisms and don't require feeding as often. I think most domestic snakes are obese compared to what I find in the wild.
