If it works, great. Me personally I prefer to feed smaller prey. Vicky who is just a smidge over 4' was on weaned rats, I just upgraded her to small rats. And Rosey who is my 6' girl has just upgraded to small rabbits. Regarding feeding though, 10 days to me is way too soon for such a big meal. Like I said, I feed all my gals smaller prey on a 3-4 week schedule except Dottie who just recently started eating again after her 5 month winter fast. I'm feeding her on a 2-3 week schedule. If you read a post I put up about how snakes change physically after eating(heart can get 140% of normal and their lungs, liver and everything else doubles in size as well and the effects can last 2 weeks), definitely makes you rethink how often to feed them. Especially the guy who fed his boa a squirrel he shot in backyard once a month and that boa lived into its 40s. That's crazy.
