Cat's Nose
Did you know?
"A cat's nose has 17 million nerve cells, which he uses to trace all smells/aromas in his environment. Even the food they eat is chosen by the smell. A cat who has a cold, doesn't eat not because he isn't hungry, but because he can't smell the food."
Comparison: A dog's nose has 147 million nerve cells; we have 'only' 5 million nerve cells in our nose. "
