Cats and dogs have significant differences in vision, hearing, and sense of smell:
1. Cats have better eyesight than dogs, especially at night, and their field of vision is also wider. Cats can distinguish blue, green, and some red, but their red vision is weaker; dogs are not sensitive to red and green, and can only recognize blue, yellow, and gray.
2: Cats have a wider hearing range, able to detect high frequencies above 50,000-60,000 Hz, which is about three times that of humans; dogs can hear sounds from 38,000 to 50,000 Hz, which is also far greater than that of humans.
3: Dogs have a far stronger sense of smell than cats, possessing approximately 125 to 200 million olfactory cells, enabling them to distinguish a variety of odors and making them widely used in fields such as criminal investigation and search and rescue; cats have approximately 99 million olfactory cells, which are also quite sensitive, but not as sensitive as dogs.
In conclusion, cats have a slight advantage in eyesight and hearing, while dogs have a clear advantage in smell.
