You know, that's funny - when it came in a pink & purple box, it was thicker, but now that it comes in a white & blue box, it's thin and watery! Smells about the same to me (not that I'm a cat) - I've had a watery one plugged in for about a week now, and didn't even notice when I plugged it in. Wonder if it lasts as long.
