The last 2 feeds I didn't have to do the dance, in fact Kitty didn't want me to. He kept ignoring the food and trying to get out, or searching as if he could not find the food, so I left him alone and in the next 30 min ratty was gone. The last time I just put the rat in there and Kitty just started to eat it, no constriction or striking. I am not sure why it changed but so long as he eats I don't much care.
