Celebrity cat Lil Bub has published a book, helped raise money for animals in need, and racked up 2 million Instagram followers  — and now, she’s had her genome sequenced, Science reports. Lil Bub has short limbs, bonus toes, and a tongue that’s always sticking out. The people of the internet crowdfunded $8,000 so geneticists could figure out what, exactly, makes Lil Bub so special. They found two notable mutations, including one in a gene associated in mice and humans with osteopetrosis, which causes short stature and dense bones.
