"Whether they're talking or not talking, kind or malevolent, supernatural, alien, or just your above-average pet, some of the most beloved television characters of all time weren't human.
A non-human creature doesn't have to be a protagonist, like in "Animaniacs," "Invader Zim," or "Bojack Horseman," to add a certain kind of charm to a TV show. Whether a sinister, otherworldly being like Bob in "Twin Peaks," a beagle who pretends to be the Red Baron, a rabbit with a Brooklyn accent, or an infant version of Yoda, non-human characters have frequently become just as iconic as the shows that they're from."
