好奇心害死大猫！ It bit the male lion s balls hard, and it was so painful to be taught a lesson in seconds.

Children are lively and active, full of curiosity about everything, so they often do things that make their parents dumbfounded. The same is true in nature.

A tourist in Japan captured the funny interaction of a family of four lions at a zoo in Japan. He saw that the young lion was very interested in the male lion’s testicles, and actually opened his mouth to bite it, causing the male lion to turn around and chase after him in pain.

Japanese netizens posted on Twitter, sharing photos of a lion family at Asahiyama Zoo in Hokkaido, Japan. They saw two lion cubs following the male lion, curiously staring at the testicles on the back of his butt. One of them even boldly jumped forward and took a bite.

After being bitten, the male lion felt hurt and angry. He immediately turned around and chased the cub, trying to teach it a lesson. After the lioness sensed the movement, she hurriedly jumped out to stop the male lion, hoping that he would calm down. The naughty lion cub looked at his father in horror.

After netizens saw the funny photos, they couldn't help but laugh and said, "Dad Lion looks hopeless", "This dad is really dedicated, he actually brings his own toys to amuse his children", "What bad intentions can a kitten have?", "Children's curiosity is really scary", "Dad Lion's hard work has no end."

In fact, the lion family at Asahiyama Zoo has always attracted the attention of tourists. The two lively and cute lion cubs often do things that make their parents angry, and this is not the first time that they have "used their brains" on the male lion's testicles.

A photographer captured a similar scene in December last year. At that time, the male lion was resting on his back on the grass, exposing his abdomen and private parts. Two lion cubs were having fun nearby and actually slapped the male lion's testicles with their palms, causing the unsuspecting male lion to bounce back in pain.
