I was hoping to weigh her before I fed her...well it turns out that FIVE MINUTES after I fed her the postal guy showed up with the scale. >.< Literally. And She just shed and defecated yesterday. It would have been nice to know he was coming today. Haha. But anyhow, if I wait two days after she eats, considering she just shed and defecated yesterday, how close to her empty weight will the new weight be?
