Pumping her up!?

[Skeet]

I finnaly got jezzy eating regularly. the only problem is that she'll only eat live, but she's good, and goes right for it as soon as i drop it in. she ate like 2 times in two moths before i got her eating normaly. it been a month and she's eaten every time i offer her live, but she's still really skinny. i have been feeding her a small rat every 7 days. can i speed the feeding up to 5 days? she only poops durring her sheding. so she only poops like once every three to four weeks. i'm afraid to offer her a second live rat incase she's not interested(i had a bad experience with giving her a live one when she didn't want it, basicly i got bitten by both the rat and her and she still didn't eat it.)
anyways any help would be appreciated.
