Haha, I saw this last week as an animated gif, good to see the full thing.
I've tried to get my cat to sit on my roomba but she wouldn't have a bar of it!
I had my roomba before I got my cat so she grew up with it since she was 6 weeks old. She doesn't hate it, she'll sit a couple of metres away and watch it but she'd never ride it. They're quite loud when they're running so I can understand plus she's a British Shorthair and they're a bit weird anyway
