To be honest I only clicked the link to see a video and I am happy I did. I love messing with my cat. They think they are so clever and in control, it always good to put them in their place sometimes.
I am so happy to have seen this. Six month old kitten is constantly trying to chew on the cables behind the television. Combine it up with one of her favorite screensavers so she plays in-front of the tv, and all should be well.
Hopefully the camera isn't always positioned with the blender in view, as I can imagine the case where the rig never turns off due to the motion detector.
Wouldn't the cat eventually learn that nothing happens besides the noise and light? They're rather smart, aren't they? (I've never owned one to be honest.)
