Lil Bub's appearance is due to myriad health issues and birth defects, including feline dwarfism and osteoporosis. The result: her legs are disproportionately stubby and cause mobility problems; her lower jaw is underdeveloped and she has no teeth, causing her tongue to stick out at all times; she has an extra claw on each foot; and she makes weird, yet amusing, noises in place of meows. She's also a "permakitten," meaning she stayed her four-pound size throughout her life.
The amount of money Lil Bub has earned has not been disclosed, but it's enough that Bridavsky was able to quit his full-time job years ago. Lil Bub has reportedly earned $30,000 a year in YouTube royalties, and donated more than $200,000 to animal charities through her ASPCA-linked fund.
But in a newsletter to Lil Bub's fans this weekend, Brivadsky announced that the cat had died "unexpectedly" after "battling a persistent and aggressive bone infection." She was 8 years old.
