I just remembered another one that my mom's sister used (she is also a cat lover and I think when they were kids together on the farm they coined all these phrases watching the barn kitties).
When a kitty lays on his or her side and stretches WAAAAAAY out, with the back curved, and all 4 legs stretched way out, my aunt called that "zooming". I have not caught a picture yet of my kitty zooming, but I'll bet some of you have - if you have one, could you share it with the group?
