I got a good laugh out of this thread! Well, Sassy can care less about the vacuum but if it was the rumba she would be attacking it. We had my moms friend bring it over a couple of months ago to see if Sassy was ok with it before we purchased it but she just attacked it. If you pass Star with the duster she flaps up a storm and that is AFTER my mom vacuumed. When your cleaning Stars cage she likes to play "bite the hand". It's cute but bad at the same time.
