Doesn't work with my cat, she walks over me (fat little one too at 14 pounds!) and if that doesn't get me up she'll find ways to make noise, I had a metal heat sink on the floor once (don't ask) she found out if she batted it about it made a nice noise! My vertical blinds, they make that clacky sound when they're ruffled... guess what she found out! Also she chases the other cat too galloping down the halls, tackling each other, etc all makes enough noise to get me up. I supposed if I had carpeted floors instead of wood it'd be less noisy, but I'm not going to install carpet just for my cats... plus they might like that too much.
