"I have always been fully transparent about BUB's health, and it was no secret that she was battling a persistent and aggressive bone infection. Even knowing this, we weren't expecting her to pass so soon or so abruptly without warning. I truly believe that she willingly made the decision to leave her failing body so that our family would not have to make that difficult decision ourselves."
The polydactyl cat was born with feline dwarfism and other genetic mutations that kept her kitten-sized for her entire life, with huge eyes and a protruding tongue.
She was an internet sensation who frequently traveled, bringing joy to her legion of fans. She had nearly 828,000 followers on Twitter.
Bridavsky said his cat helped raise awareness and funds for special needs animals.
"But most importantly, BUB has made a huge difference in the world of animal welfare, and in the lives of millions of people worldwide," Bridavsky said.
"She has literally saved thousands of lives (both pets and humans), she started the first national fund for special needs pets, she was the subject of groundbreaking genetic and biological research, she's helped raise over $700,000 for animals in need, and has spread a message of determination, positivity, and perseverance to people all over the world."
We are very sad to hear about the loss of Lil Bub, who was well-known for her adorable and unique look. Along with being a sweet kitty, Bub was an advocate for special needs pets and raised over $700,000 for animals in need. She will be missed by many. ❤️https://t.co/HpXbY3DTZY
