Lil Bub is perhaps the most interesting cat on the Internet, and she enjoys a hefty fan base. She’s instantly recognizable due to her unique appearance: large green eyes, a short snout, and a tongue that is perpetually sticking out. She also is small and has very short legs, has extra digits on her paws, and sadly has no teeth. The reasons behind this are believed to be DNA mutations, something a pair of researchers want to definitely pinpoint. Thusly, they’re going to sequence Lil Bub’s genome.
