I have a Jardine that I've had for 13 years....she is just as you have stated..feisty.
I love this about her. I don't want the idea of her feistiness to detour you from a Jardine.
Feisty is only one quality of Sugars..she's a nut, very comical, loving, a good talker, and curious. She has been a joy to have in our lives.
I have been bitten by her, however I now beleive they were to get me to fly away due to a preceived danger..something I've read that they do to their mates in the wild.
