My pastave girl is that way. When I fed them on Monday, I had the plate with her second rat on it and she tried to drag the rat she was already working on, out to where the second was laying. It was cute but I made her eat one at a time. Last night, she got all excited when I went in to do my evening check. I was all worried about having balls because of the feeding issues I'd read about. She's as bad as my corns though and they'll eat anything in any amount if I'd let them. I'll have to post video of my most aggressive feeders. He'll grab my finger when I get him out on feeding day (the corns are fed in separate containers), eventually figure out it's not food, grab and coil the f/t meal, gobble them down, and then grabs my finger again on the way back to his cage. It's ridiculous!
I wouldn't mind the weight gain either though as my pastave put on 125 g. the first month (empty weights). She's on track to beat that this month and she's not fat. I swear she's growing noticeably every week!
