-- Meet Bum, a cat from San Diego, California, who looks worried all the time.
But no worries! This cat is just fine and is "actually super silly and happy," his owner Courtney Morman told ABC News today.
"He just has perpetually crossed eyes," Morman, 24, said. "His eyes and lids are also shaped a little funny, but other than that, he's totally fine. He's been seen by a vet and nothing is wrong with him."
Morman added she believes her "crossed-eye cat" has "sharp vision" and noted that he "loves to catch bugs and chase down toys."
"I fell in love with him instantly," she said. "When I first saw him, I thought he was the cutest kitten ever, and his personality matched his silly looks."
"Bum can be shy at first with new people, but when he gets to know you, he's so loveable, silly and smart, she said. "He's really smart and he loves to go under the covers and cuddle in the mornings."
Morman, who often fosters pets at shelters, added that Bum "loves all animals" and used to be best friends with her late cat, "Admirable Kitty Kingman." Though Admirable Kitty Kingman recently passed away, Bum continues to be "a great foster brother" to other kittens who come into their home, she said.
"He's helped raise a few litters and is a wonderful companion to other cats we take in who are recovering from injuries," Morman said.
Bum also has a dog brother named Leo, who Bum "definitely wants to always play with," but since "Leo doesn't want much to do with Bum," the two just chill out together and "co-exist," she laughed.
Morman said she hopes that Bum's story helps bring smiles to people's faces and encourage those looking for pets to "adopt, not shop."
