Cats have a more sensitive sense of smell than dogs. Cats have 20 million more olfactory cells than dogs.

The dog's sense of smell can be used in the military and police to help search and rescue, solve cases, etc.
The cat's nose has a very special structure. There are many folds inside the nose. Its olfactory organ is located deep in the nasal cavity, called the olfactory mucosa. Its area contacts air is very large, reaching 20 to 40 square centimeters, three times that of a human. It contains more than 200 million olfactory cells and can smell the musk smell diluted into one-eight million. When the odor enters the nasal cavity with the inhaled air, it can stimulate the olfactory cells to cause excitement, which will be transmitted to the brain along the olfactory nerves, thereby causing the sense of smell.
