@Skethcy:
My mom has, but only because she does with my older girls.
I've only had here for a little over a week, two on Friday. She's only about 7 weeks old.
She only bites when you get near the cage though, when you handle her she doesn't, only mouths.
I take her out everyday, for a good amount of time, because I'm trying to socialize her more.
She doesn't seem like she's doing well though. She's extremely thin, I mean I can feel all her ribs and her hips, and I know she eats, we feed her all the time. She won't open her eyes too far, and they don't look very bright from what I can see. She won't move too much either. I had to put her in quarantine not too long ago, and I'm hoping I'm only overreacting, I'd be really sad if she was to pass.
It annoys me though that my sister doesn't care, I mean it's her rat, not mine, and as much as I've become attached to her, she's not mine. I just wish she would show a bit more compassion towards the little baby.
