Step aboard the USS Enterpaws! If you're a Star Trek fan, then by golly your cat sure better be a Star Trek cat! Not an alien cat, or anything like that, more so just a cat that also likesStar Trek . . . or at least appears to like Star Trek . . . In any case, whether your cat is a legit fan or just a poser reppin' the Star Trek logo to impress his / her friends, this Star Trek: The Original Series Blue Uniform Cat Collar is a must-have. Please keep in mind that just because your cat is wearing a blue sciences / medical uniform from Star Trek: The Original Series, doesn't mean they can perform surgery. But it's nice to dream, right? For cats 8 to 12-inches neck size.
