The temperament on all 3 is much the same. Just a little skittish as I work a lot and sometimes don’t have time to handle much. When I do handle them it is always with open hands and I try to be gentle and predictable. They tend to be all hiss and no snap.
I would say that Betty is the calmest of the three. But don’t get in the way of her feeding response as Cody learned a few weeks back. She mistook his hand for a rat and both were very surprised to say the least.
