I'm going through that with my 4 year old, male boa right now LOL!
In the last 2 weeks I've tossed a rabbit, a rat and a really nice quail.
The good news is I'm dropping temps shortly and he'll be off food for a few months coming up fairly soon. I do want him to eat at least 1 more large meal before we make the drop though.
Yes, the babies are always fun! Although out of my 4, the boa and the retic are the only ones who've been consistent from day 1.
I don't see this guy eating more than large rats, large quail, or max, 1 pound rabbits. My plan is a 7-9 foot male retic. He has plenty of SD and Dwarf in him to stay 11 feet or under. At least I hope.
