I dont think feeding her a jumbo a week is going to make her obese. I mean it might be a bit different for a super dwarf but a lot of the people i see on the retic forums seem to feed weekly. I mean i guess if you are worried, you can always just feed on the smaller side but more often. That way she isnt sitting long with a empty stomach but also isnt stuffed like a turkey 24/7.
And same here, Caesar usually starts wandering around and getting really alert around the 5th day. Since i moved him up to jumbo rats weekly, like i said, he has been really laid back and doesnt push anymore. He's in shed right now so he's extra quiet except for when he shoves his warm hide out of the way so he could sit on the flexwatt uncovered haha. He seems to not even care for his hides too much anymore right now.
As for size, while i agree, feeding will play into the size, i think genetics has a lot to do with it too. I mean look at Wallace. Gio fed him a small rat every 14 days and he's 5.5' or so. I fed Caesar large and jumbo rats and he's about 6.5'. Thats a huge difference in food intake and Caesar being i think almost double the mainland blood and half the dwarf blood of Wallace and he is only about 1' longer. Now if you fed Phyllis her max every few days, she might get big but i still think the genetics will top them out. I mean no matter how much you fed Phyllis, she would never become a 20' snake. Her genetics just arent programmed for it. At least thats what i think. And i feed Caesar weekly most of the time. I mean sometimes he's goes longer if he is quiet. Like now he is in shed and hasnt eaten in probably close to 1.5 weeks and he is still quiet. I mostly just feed when he gets active and starts darting at any movement as that seems to be his signs when he gets hungry.
