My male JCP, Simba, is the only one of my carpets left that will still try and bite my face off. I've been working with him so much that i just don't understand why he's still so hostile . . . so I walked in and found my dog jumping up at the cage and simba being defensive as ever. It's a classic case of "haha you can't get me because of this magical force field" if i've ever seen one . . .
