Zincubus, let me preface this by saying I have gotten to "know" you pretty well through this forum and I have nothing but the utmost respect for you, so please don't take this in a negative way. I don't think you will, but wanted the disclaimer out there....
I always get a chuckle when you discuss your Kings' feeing responses. I can almost picture you (without having a clue what you look like) feeding your Kings and just love the image I have created in my head, Hahahaha!!! Anyway, hope you took that the way I meant it. You're one of the people on the forum I have 100% respect for and would never mean to give you anything but the compliments you deserve....
Like most Kings, my boy Django has that insane feeding response, so I completely get what you're saying. I just open his enclosure with his mouse close by and he's all kinds of fired up and there are times he comes flying out the top to get his prey. It's hilarious!!! So, I get it. I just dangle and let him do his thing. Sometimes he'll miss more than once, sometimes he'll strike at a shadow, sometimes he'll try to strike me through the glass.... it's hilarious to me. I love my crazy boy to death and his feeding response is part of what I love about him.
