Lil Bub Dead, Viral Celebrity Cat Passed Away In Her Sleep

Lil Bub, one of the first cats to go viral on the internet due to her precious appearance and uplifting backstory, has passed away at the age of 8, TMZ reports. The animal died peacefully in her sleep.

Health Issues And Deformities

The odds were stacked against Lil Bub from the moment she was born. The runt of the litter birthed to a feral mother, the animal had a number of physical deformities and health conditions that made it difficult for her to find a forever home.

However, her human, Mike Bridavsky, was smitten with the sickly animal almost from the word “go,” saying that he chose the name when he picked her up and the first words out of his mouth were, “Hey Bub!” as The Daily Beast reported in 2013.

However, Bub required a tremendous amount of TLC. She lacked teeth, which meant that the helpless kitten had to be bottle-fed. She had an extreme form of feline dwarfism, making her limbs small in comparison to the rest of her body and making it difficult for her to walk as well. Her lower jaw was short, causing her tongue to constantly hang out. She also had osteoporosis.

Additionally, though it didn’t affect her life, she also had extra digits on her paws, an uncommon, though not particularly rare, genetic trait among some cats.

Viral Fame

In 2011, Bridavsky posted a picture of Lil Bub on Tumblr before the photo eventually caught the attention of Reddit. From there, she became a viral star, as internet users the world over couldn’t get enough of the cute cat whose can-do attitude and perpetually-extended tongue warmed hearts everywhere.

Soon there were innumerable memes of Lil Bub all over the ‘net. That led to a book deal, a movie deal, merchandising deals, and an Instagram page with over 2 million followers.

A Serious Side

It wasn’t all just fun and laughs when it came to Bub’s fame, however. She was also the subject of a scientific inquiry. Researchers wanted to map Lil Bub’s genome to get to the bottom of what caused her physical deformities. Ultimately, the cause was identified as a mutation in gene RANK/TNFRSF11A.

A Sad End

Unfortunately, Lil Bub’s multitude of physical problems eventually caught up to her. Specifically, it was an aggressive bone infection that claimed her life, at the relatively early age of 8-years-old.

The first two years of a domestic cat’s life are roughly equivalent to 25 human years, and each year after that is roughly equivalent to four years. In other words, in “human years,” Lil Bub died at the equivalent age of about 49, or that of a middle-aged human woman.
