Bum is an adorable kitten that has been going crazy viral on the internet lately due to his permanently worried expression. In addition to his slightly crossed eyes, Bum’s fur around his eyes and the color of his fur all make him look like he’s always concerned about something when he was brought into the San Diego Humane Society shelter when he was four weeks old. Interviewed by LoveMeow, Courtney of the Sand Diego shelter said that “He is shy with new people, but once he knows you he is a love bug. He loves morning cuddles and to sleep under the covers! He also loves other cats, especially kittens, and has helped raise multiple Foster litters and even spend time with injured ones who are being rehabilitated”. Take a look at more images of Bum on his Instagram.
