Thank you I will try. I was worried because she's NEVER hesitated for one second as soon as a rat comes near her she strikes and constricts. The few times the rat came near her (she always had the wobble before striking with frozen and thawed, never with live) she got her wobble and the rat would walk away before she struck. So I tried pre-killing the rat and she still would not take it, then I started thinking she would only eat live now. Which is not the case because she has never hesitated with live not for one second. Also i've had her back and forth from live to pre-killed to F/T for different periods of times and it has never affected whether she will eat. But i've always had her on a seven day schedule so she's always had time to poop first and that may be it. I will be getting a kitchen scale that goes up to 5000g from wal-mart soon.
