So....

I need some expert opinions. I think my new female may be gravid. She got pudgy real fast, I just assumed she was packing on some weight but now I think she could possibly be gravid.

Looks to be ovulating, not quite gravid yet.

Agree'd.

She's up to almost 50 grams now, but it's been steady weight gain and not just poof she's chubby all of a sudden. I like the size she's getting, maybe she'll be a giant after all! ;D

Her torso doesn't look long enough to me for her to be a genetic giant, but the sudden weight gain could be the onset of winter fat storage plus a growth spurt that happens at certain developmental stages and the addition of ovulating. Girls have a lot more going on than boys do when it comes to drowth and development. I noticed with Eros that there were times where he looked kinda lean then in a week he looked kinda chubby, then he'd grow in length and the chubby would be gone and he'd look lean again. Use the tail as your best way to monitor fat storage and growth. If the tail isn't changing much then she isn't packing on fat weight but growth weight such as muscle and organ development.
