The fans of internet-famous cats had a tough year. With Grumpy Cat’s passing in May, more bad news just reached us. A couple of days ago, a goofy-faced kitty named Lil Bub passed away, too. Yesterday, his owner Mike Bridavsky announced her death on social media, with a heartwrenching tribute, mentioning all of the good deeds the beloved feline has done.

Lil Bub became a viral sensation soon after her first photo was posted on Tumblr in 2011. Quickly, she gathered over 2.4 million fans on her Instagram page and became one of the most recognizable cats on the internet.

What people loved about her the most? Clearly, her unique, overwhelmingly adorable looks are to blame. Lil Bub is known for her short snout, tiny limbs, big round eyes and a tongue that’s always sticking out. It is widely known that her signature looks are a result of several genetic deformities.

In 2015, scientists even crowdfunded a campaign so they could sequence Bub’s genome. The scientists wanted to find out why the feline has extra toes on her paws and no teeth. They also had questions about Lil Bub’s peculiar bones, called Erlenmeyer flask bones, that are much thicker than the bones of a regular cat.

Being the runt of the litter, Lil Bub required special care since her birth. Luckily, she had an amazing owner who took care of her. Bridavsky has always been open about his cat’s health issues. He says that Bub’s passing was unexpected for him.

Even though the poor cat was battling a bone infection, Bridavsky believed that it was not the time for his 8-year-old buddy to go just yet. However, two days ago, she passed away peacefully in her sleep.

Beyond being cute and a little bit different, Bub has made a difference in this world. She was an advocate for homeless and special needs cats. Lil Bub helped to create Lil BUB’s Big FUND for the ASPCA which is the first national fund for special needs pets. The feline raised over $300,000 for animals in need.
