Could she still be hungry???

Don’t mean to sound dense but what is maintenance fed? We finally were able to weigh her and she is 147.5 grams, roughly 18” long, and her widest bit is about 1”.

What some euphemistically call "maintenance feeding" means that the animal was fed minimal amounts of food to minimize growth; it's what some breeders do so the offspring don't outgrow their caging or their "cuteness", since many buyers prefer to buy "baby" snakes, while their bites are just tiny nips, etc.
