Many cat owners feel that they already know their little ones well, but there is never a shortage of surprising situations in the world. The following knowledge about cats is hard to believe at first, but they are all true. How many of these knowledge do you know?

Cats can taste the smell of water. The tip of the cat's tongue has a "water receptor" that allows them to distinguish the taste of water. The existence of this receptor is to allow cats to replenish water in time and metabolize excessive salt intake from meat when they are dehydrated.

Cats can't see things up close. A cat's eyes cannot focus at close range, and only distant things can be seen clearly, so seeing things at close range is equivalent to semi-blindness.

Cats can hear better than dogs. Dogs can hear vibrations of 1 million hertz, while cats can hear more than 4 million, so cats can sense the coming of an earthquake 10-15 minutes before.

Cats have 24 whiskers. A cat's whiskers are very important to cats. There are 12 whiskers on each side of the cheek. They are used to sense the surrounding environment, just like the human hand.

Cats sleep 70% of the day. In order to replenish energy, cats purr much more time than other animals. The snoring time is 12 to 16 hours a day, and some cats can even sleep for up to 20 hours! However, during these snoring hours, only 30% were in the sound sleep period, and the rest of the sleep time was in the non sound sleep period, and it was easy to wake up.

A cat's heartbeat is almost twice that of a human. Have you ever heard your cat's heartbeat? Have you ever wondered how their heartbeats are so fast? In fact, don't worry, a cat's average heart rate is 140 to 240 beats per minute, which is almost twice that of the average adult male. It's also easier to test your cat's heartbeat, just put your hand on the cat's left side, behind the front leg, and feel their pulse on your fingertips. Then, take 15 seconds to count the number of heartbeats, and you can calculate the cat's heartbeat per minute.

A cat's ear has 32 muscles. Some pet owners say they can tell if there is something wrong with their cat from the shape of their cat's ears. This is because a cat's ear has almost 32 muscles that can change in different situations. For example, when a cat's ears are flat and close to the head, it's a sign that the cat is uncomfortable or scared.
