Yeah all my snakes are on the eternal summer. The funny part is how i keep them on an eternal summer and you fast but your male is about 6" bigger and maybe heavier. Rosey is about 6.5' and 13.7 lbs. And they are both about the same age as we got them at around the same time i believe.
I just feed less in the winter and more in the summer. And yeah, Rosey was fed fairly healthy the first year when she was a baby as she was my first boa lol. That's kind of why I'm surprised she is actually smaller than your male.
