Scaredy cat

Lost cat detection "idea"

Have you ever noticed how a scared and puffy cat has a distinctive odor? It's a faint mix of cat urine and dead skunk, just barely detectable.

So, since we're able to train bees to detect land mines (click here for details), couldn't we train bees to track that scared cat smell? Thus, if you lose your cat (most of the time they get stuck or are hiding somewhere close to home), you'd release these bees and track them over the next three days. Where they start congregating, you know you have a cat in need.
