Our ball has trained us to read a different meaning with some of her body language: "I'm hungry".

When Cleo is hungry, she a third of the way out her hide, hovering, slightly S'ed and "throbbing" or "bouncing". She is so excited and ready to eat, her weight must be near where her heart is and her heartbeat causes her front third to bounce. =)

If she's not bouncing, she's not hungry (or at least she hasn't eaten in recent history when she wasn't exhibiting this body language).

She was so excited last night, she even struck at glass - "HUNGRY NOW!" She let's us know, hehe...
