A / N: I just felt like writing this, so go figure.
Disclaimer: I do not own Star Trek, if I did it would be real I would be living on Vulcan. So probably better that I do not.
Jim Kirk - Domesticated Fox Called Red (Well, by then there might be domesticated foxes. Both are sly, cunning and loyal (?).)
Spock - Green Iguana called Mazhiv Im'roi (Both like deserts and only eat plants, so it's a perfect match. Oh, the name means sand Walk.)
Leonard 'Bones' McCoy - Gold Fish Called Goldy (Ah, a pet that can not talk back. Cats. ... Now they talk back.)
Hikaru Sulu - Pica called Katana (such a sweet little rodent, not Sulu ofcourse)
Pavel Chekov - Green Parrot called Vodka (Some can live in colder climates!)
Nyota Uhura - Siamese cat called Grace (Cats just seem to suit her.)
Montgomery Scott Scottish terrier called 'Scotty' else (What?)
A/N: If your thinking WTF, it's perfectly alright. That was my impression after rereading this.
