Dean, he's been going about once a month. (When I was having all the problems with feeding response biting I moved him from every seven days to every five- he'd been on a weekly schedule at the breeder's, and that's when his growth really took off, too, going by the total weight of prey suggested on the Munson Plan, but split between two or three prey animals, due to recommended caution with prey size for Tri-Colors) Addy, the Eastern, has shed twice since November. His ventrum is a beautiful robin's egg blue/silver- and he almost looks like he's about to burst open. On my monitor at work, he just looks dull gray.
When I had him out to weigh him last week, he started doing the convulsing hiccupping mating thing- Pineapple!!
If I was going to breed anything, I suspect Tri-Color Hoggies would be a cool thing to start with.
