We don't usually need a dance, but we do have a bit of a ritual. First, I put the frozen mouse on the shelf next to her tank, so she can see a mouse(this gets her hungry pretty fast). Then I stand in front of her and dunk the mouse in and out of a cup of hot water. She locks on to it and gets into that striking pose. Then it's a little game to see if I can get the mouse hot enough for her to take it, then dry it and give it to her before she strikes the glass. If she's ready to eat, all I need to do is dangle the mouse an inch or so above her face. She looks up and the mouse is taken.But I have to be quick, because if it's there longer than ten seconds or so, the mouse cools down. And if she smells it cooling down, she figures out it's dead, and no amount of reheating it will get her to take it.
She will refuse a mouse if I don't stand in front of her with the water. Like I have to do that or else it's not time to feed. And way back when I fed her in a box instead of in her tank, she'd 'kill' the mouse, but wouldn't eat unless I was sitting next to the box. She has some weird issues.
