Black and white cats recognize their owners. Black and white cats, also known as cow cats, are docile and loyal cats. Cats have a well-developed sense of smell. After a cat owner gets along with the cat for a long time, the cat will remember the owner's smell, and over time, it can recognize the owner through the smell. In addition, cats can also distinguish the owner's different frequencies through hearing and distinguish the owner's different body language through movements.

How cats can identify their owners:

1. Through smell. Cats have more than 200 million olfactory receptors in their nasal cavities. Their sense of smell is very sensitive. They can easily distinguish more than 20,000 odors. Everyone's odor is different for cats, so cats can use their sense of smell to quickly distinguish out of one's own master.

2. Make marks. Cats are animals that are good at marking. They like to rub against their owners. They don’t simply want to get close to their owners, but they want to leave their own scent on their owners.

3. Distinguish sounds. Cats' hearing is very sensitive, and their hearing range is 60 to 65,000 Hz, which is far higher than the human hearing range.

4. Through behavioral habits. A smart cat can remember the owner's behavioral habits, such as walking posture, gestures, etc. When the cat has been with the cat for a long enough time and the cat understands it well enough, it will be able to understand your body language very well.
