I was curious about the same thing, thanks for asking this, so I'd love to hear some reports on other people's female's weights at around 9 months and one year or more.
We know not to breed them until at least a year and until they're of sufficient size, I think the point is that we're (or at least I am) new to the size of female panthers. They looked bigger in the pictures! Maybe they're always feisty. Lol. Just now that I have her here, i know she still has a few months to go, but she just seems small compared to her big ole boyfriend.
Other question is, I've heard before that some locales are just generally larger than others (I know my mitsio is quite a lot larger than my faly) so, does the locale size thing apply to the females as well?
