This kitten named Bum has become an "Internet celebrity" on foreign social networks with its cute cross-eyes.
Born with opposite eyes, they always look anxious, pitiful and cute.

Bum lives in San Diego, California, and was sent to an animal shelter when he was only four weeks old.
Bum's cross-eyes always look very uneasy.
The staff said that Bum is a little shy of strangers, but once he gets to know him, he is very clingy.
It likes to sleep under the sheets, play with other kittens, and will take the initiative to accompany injured cats.
Fortunately, Bum has found a new home. The owner, Courney Morman, posted his photo on the Internet, which quickly made many netizens cute.
Bum’s owner, 24-year-old Courney, also works at the animal shelter. She said Bum is very cute and helps take care of other cats.
Although Bum cannot change his eyesight, there is no problem with Bum's eyesight. He also likes to chase various toys and is best at catching bugs.

Despite his anxious look, Bum is actually a happy cat who likes to play with cardboard boxes and always sleeps on his owner's face.
The owner said that Bum is very smart and even learned to open the bag, open the drawer and unzip it without any teacher. "If it wants something in my bag, it will unzip it and get it by itself. I have to lock everything up."
This year Bum is almost two years old. The owner said that he hopes to use Bum's appeal to call on people to do more to save stray cats. "I want people to know that I have a super cool cat, and he was rescued, not bought."
