Retics are still reptiles and reptiles have evolved over millions and millions of years to sustain themselves during long periods of famine. Just because something is a retic doesn't mean it is open season to give it endless food. JM and I SD x dwarf retics for a reason. They are smaller. They are from island populations that have seasonal peaks in feeding. Seasonal migration of certain bird species to those islands, mating and birth cycles of other mammals, rainy season, and other events play a role in their feeding and adult size.
Though they are more active than the average boid, they are not made up the same way as some of the colubrids that actively forage.
Feeding SD retics in theory should mimic their natural food cycles. They should have some prey variety, some variation in prey size and frequency and you as the keeper should observe their individual needs.
It is well known and stated by more than a few experts that a male SD and dwarf retic can thrive and live a long healthy life by eating 1 large rat a week. Females may take a bit more, but if you are not breeding them, there is no need to stuff any snake unless you want it big.
I'm doing just fine feeding my snake 1 small rat every 7-10 days and have had zero issues.
JM,
Find what the snake wants/needs and go from there but I'd always stay conservative.
Gerald is a beauty!!
