Popcorn runs boldly, and hisses at the vacuum, trying to scare it away. He doesn't seem to be to scared of it, but he stares at it from the corner of his eye, and hisses whenever it gets near.

Muffin *hates* the vacuum though. She's scared of it. Whenever we turn the vacuum on, her crest goes straight up, in a 90 degree angle, and she runs and hides, while staring at it constantly from whatever *safe spot* she chooses. LOL
