I got nothing, so how about some Wikipedia?
- Cat, a domestic feline, Felis silvestris catus
- .cat, a top-level domain
- cat (Unix), the concatenate program in the Unix operating system
- Cat (Red Dwarf), a character in the TV show Red Dwarf
- Cat (role-playing game), an indie role-playing game about cats
- Cat (kingdom), a Dark Ages Pictish kingdom
Note the Coat, Legs, Claws, Face, Fangs and Tail attribute system in the role-playing game. Nice. “I have a strong, healthy coat!” :)
