When my ball was ALWAYS hungry I knew it was time to up his prey size. You might be feeding her too small of a prey item. What are you giving her if I may ask? When my ball was a year old he was eating jumbo mice (the jumbo mice my provider sold me were retired breeders, so they equaled the size of a two week old rat). But, he was small for his size at the time because he was one of those "no I don't want your mice!" kinda balls as a hatchling. He obviously came around haha. I wish I had weights but I don't right now. Currently at 2 years he is 700 grams.
