The exact same thing has happened to my hybrid, Bramble. Her coat is changing, she's lost some weight, she's more active and demanding, she's burrowing for the first time and her hoard is massive. She constantly wants food, not to eat, but to hoard.

I did some research and found that Winter Whites in the wild lose weight in preparation for winter (less weight means they need less energy to survive) and the females become more aggressive.
