Both of ours are the same way. They were born Aug. 2nd, so they are still very young. They too will try to 'jump' out of our hands and if startled will musk/pee/poop. However, with regular short session handling the female has already gotten much better (still have to be careful not to startle her w/sudden movements) and the male is coming along as well. From what I've read/heard, they do calm down a bit w/age.

EDIT: WELCOME!!!
