Another collar that tells you when your kitty is purring. The Purrfect Mood Detector has a tiny microphone that picks up any purring sounds and illuminates its collar mounted LED light letting you know if your cat is in a good mood. Which means that if he has to wear this silly charm around his neck, he probably won't be in such a good mood, so don't expect it to light up anytime soon. The charm is available in Pink or White, and you can opt to use your cat's existing collar. Price: $14.95
