Alastor makes little screaming, almost painful sounding noises, jumps up and down on his hind legs while running around my feet, then gets the zoomies while making a whining noise deep in his throat. He jumps on and off the couch while zooming and finally ends up in front of me again jumping on his hind legs until I pick him up and hold him like a baby. Its quite the show and does it if I am gone for hours or just to take the trash out or get the mail. I think he kinda' likes me
