I have never seen AC and having two cats myself would very much like to. Would AC like a toy that is operated by remote similar to the light and bubble machine? If he had a bell on a string or a flexible stick that moved he would be more likely to visit his spot to appear on camera. Electrical apparatus that rotated (slowly) or moved like a metronome could be modified into a cat toy. Think about it and I'll look for it on the site next time I visit. Cheers to unique ideas!
