Why do cats like to sit in circles?

Cat lovers and photographers all over the world have uploaded their "circling cats" to the Internet, mainly Reddit and Imgur users. These photos show that cats can't seem to resist the charm of circles. As long as they see the circle, they will sit in the middle of the circle and refuse to leave. Veterinarians and pet psychologists are puzzled by this strange behavior of cats.

You can spell a circle on the ground with tape, and then wait for the cat to enter the circle. At present, there is no research to explain why cats have a soft spot for circles. Veterinarian Brian Falkner said that he did not find any evidence to prove that there was a specific psychological reason behind this phenomenon. He pointed out: "Cats like borders better than dogs. Cats will feel very comfortable when they see their' territory'. "

Veterinarian Ashley Gray gave an interesting explanation: "This behavior of cats seems to be related to their curious nature. You must have heard the expression "curiosity kills the cat". The way you draw circles in front of cats may make them curious and want to know,' What are you doing?' . "

Gray said, "Cats will find a safe place. This place may be where they sleep, or somewhere on the route they often take. They will leave marks in these places through magical friction and scratching. The circle may have played such a role. In the cat's eye, the circle is equivalent to the mat at the door. "

Juliet Jones, an expert on cat behavior, pointed out: "If you draw a circle on the ground, cats will think that there is a perceptible barrier around them, which makes them feel more secure than staying on the vast floor. In order to truly understand the reasons behind this behavior, we need to conduct scientific research in a controlled environment to determine whether most cats have this behavior.
