Isn't it grand to be a cat? Now kids can compete to make the cat purr the most/longest/etc. Happy, happy cats.

Now only if we could make a collar like that for humans. It could be set to be triggered by all sorts of things.

A lie detector would be great for improving society. I'm tired of all the lies.

It could be extrapolated to detect when a woman fakes an orgasm. I'm tired of... *Sigh* I guess that's not really a problem for me. If only this could be a point of personal pride.

A California company has developed a cat collar that glows whenever the cat purrs.

In addition to providing family fun, the Purr Detector can also flash when the cat is outside at night, for improved safety and visibility.

"Kids love the Purr Detector," says Vickers, "and cats love the extra attention. In addition, the nighttime flashing feature protects cats by making them more visible to cars."
