There’s something about a ginger cat.
We’ve seen the greatness that is Alien’s Jonesy. But there is another and possibly even more beloved ginger icon, with a similar arc but more screen time. Spot, Commander Data’s cat on Star Trek: Next Generation, appears in eight episodes of the series, with appearances in two of the films, Generations and Nemesis, plus a cameo in an episode of Picard.
Spot first appears in Season 4’s “Data’s Day.” The episode is a sort of diary, and it has a Theme: friendship. Amid all the alarums and excursions, we learn that Data has a cat. His name is Spot, he’s a long-haired ginger, and Data feeds him and pets him while he works at his computer.
There’s no explanation. We don’t get the backstory on how or why Data ended up with a cat. He’s just there, in the same way Jonesy is just there on the Nostromo.
Spot shows up again near the end of the season, in episode 25 (back in ancient times, TV seasons used to be 26 episodes long), “In Theory.” Again, he’s a long-haired ginger, and he’s a minor mover of one of the subplots. Data has the door of his quarters set to allow only humanoids to pass, but Geordi finds Spot outside and a couple of corridors over.
It’s a mystery, which eventually gets solved. In the process, we learn that Data has been experimenting with numerous cat-food formulas. Spot, it seems, is a picky eater.
The main plot revolves around a sweet young blonde crewperson who makes moves on Data. Data has no emotions at this point, that chip hasn’t been installed, but he’s been developing a program to predict human reactions, and he is amenable to experimenting with a romantic relationship. When the inevitable happens and she breaks up with him, he closes the episode by picking up Spot and cuddling him.
That’s the last we see of Spot until Season 6. In “Schisms”, Spot isn’t present except in verse. Data’s poetry reading (attended by a circle of overwhelmingly bored crewpersons) culminates in the famous, or infamous, “Ode to Spot.” It begins,
Felis catus is your taxonomic nomenclature
An endothermic quadruped, carnivorous by nature
Your visual, olfactory, and auditory senses
Contribute to your hunting skills and natural defenses.
It ends,
And though you are not sentient, Spot, and do not comprehend,
I nonetheless consider you a true and valued friend.
Awful? Brilliant? So bad it’s wonderful? You be the judge.
The cat himself appears in “A Fistful of Datas.” Spot is now an orange shorthair, and we have a pattern of behaviors: he often occupies Data’s lap and/or his computer console (whether Data wants him there or not), and he has, as Data puts it, “highly selective tastes.” It’s an ongoing project to find a formula that Spot will eat. Spot is, in short, a normal cat.
In “The Birthright, Part I,” in which Data first begins to dream, Spot is one of three personal things that appear in the dream: his cat, his potted plant, and his paintings. Spot is just there, part of Data’s mental landscape. But in Season 7, which is the last season of the series, he finally gets a chance to shine.
The first episode of the season, “Descent, Part II,” completes an arc in which Data is equipped with an emotion chip by his evil twin, Lore, but he’s not ready for it. When he comes to that realization, and discusses it with Geordi, Spot is present, doing cat things and allowing Geordi to pet him.
“Phantasms” continues Data’s dream journey, this time with a terrifying twist: Data is having nightmares. The episode begins with Data studying Spot as he sleeps, noting the physical indications that he’s dreaming. Data tells Troi,
“Spot has never seen a mouse or any other form of rodentia. He has never encountered an insect or been chased by a canine.”
Spot is a ship’s cat, though apparently there are no vermin to hunt on a Federation starship. He’s a pet and companion. Data is worried about harming him during one of his waking nightmares, and asks Worf to look after him.
Worf is nonplussed. “Your animal,” he growls, and commands the cat to “Come here.”
Spot is not a canine, Data reminds him. He doesn’t obey verbal commands. When Worf grudgingly picks him up, Data comes near to babbling about his care and feeding. Which supplement he likes, he has to have water, he has to have a sandbox—
“And you must talk to him. Tell him he’s a pretty cat and a good cat…”
“I will feed him,” snarls Worf. That, Data realizes, will have to be enough.
It does seem to be. After Data’s nightmares have been resolved, Spot is back in his quarters again, and Data is teasing him with a fuzzy toy on a wire. As one does.
In “Force of Nature”, Spot has her own major subplot. Geordi has borrowed her in an effort to find out if he wants to get his own cat.
Her. Right. We’ll get to that.
Spot has been manifesting major cattitude. She’s smashed a vase and a teapot, scratched a chair to pieces, and coughed up hairballs all over the carpet. Now she’s hiding under Geordi’s bed and he wants (entirely metaphorically, one hopes) to kill her.
Well, says Data,
“When you borrowed Spot, you said you wanted to experience the full range of feline behavior before getting a cat yourself.”
The answer to that question, Geordi says fervently, is no. He is not ready for a cat. He then tells Data to call her.
Data can’t do that. Spot doesn’t do verbal commands. Well then, Geordi declares, you need to train her.
Data’s attempts to train the cat provide comic relief in an otherwise harrowing episode about, among other things, the ways in which warp drives are endangering the universe. Data concludes after a long and varied series of experiments that she may be inherently untrainable; maybe she lacks the intelligence to process human commands.
While he tells Geordi this, Spot meows at him. He pauses. She meows again. He fetches her favorite string toy and starts to play with her.
“I don’t know about Spot,” says Geordi, “but seems to me your training is coming along just fine.”
Seems to me the cat may be rather smarter than Data recognizes. As for intelligence or lack thereof, it may be worth noting that Data had to prove his own sentience in order to be admitted to Starfleet. The fact that he makes a repeated point of Spot’s lack of it, and yet is so clearly bonded to her (or him), is an interesting and ongoing theme in the series.
The main plot of episode 9 involves an alien scientist who has made a devastating and controversial discovery. No one believes her. She resorts to ever more desperate and aggressive measures, which backfire badly.
Data’s attempts to train the cat are a much gentler reflection of this plotline. They’re teaching a lesson about the difference between persuasion and force.
In Spot’s final episode in the series, “Genesis”, she finally becomes a main character. Spot is pregnant, and Data has been with her every step of the way. He doesn’t know which of the twelve male cats on board is the father—he plans to run the kittens’ DNA after they’re born—but he does know that it happened during one of her escapes from his quarters.
Meanwhile, crisis of the week means that Data may be away from the ship when Spot has her kittens. He entrusts her to Reg Barclay, the only human on board whom Spot seems to like. (Spot is quite expressive about her feelings toward other members of the crew. As in, physical injuries.) Reg seems to adore her, and he knows cats: he understands that she’ll want a dark and secluded place to give birth.
While Data and the captain are away, all hell breaks loose. They come back to find the ship shut down and the crew transformed into prehistoric animals. Spot, when they find her, is an iguana.
But her newborn kittens are still kittens. The placenta, the maternal antibodies, and the amniotic fluid all protected them from the evil space virus. That’s the key to the antidote. With the help of a pregnant crew member, for humanoid amniotic fluid, Data whips up an antidote. Spot has saved the day.
That’s it for Spot in the series. She (or he) appears briefly in Nemesis, but in Generations he (or she) is a catalyst for Data’s major emotional breakthrough. After the total destruction of the Enterprise, as Data and the rest of the crew comb through the wreckage in search of survivors, Troi detects a small life sign in a heap of rubble.
It’s Spot, and Data gathers her up, sobbing into her fur. He’s discovered complex emotions. “I am happy to see Spot, yet I am crying.” He’s spent his life trying to understand what it’s like to be human. Now he knows.
Spot is a constant in Data’s life from Season 4 onward (and possibly throughout, but we don’t meet him until halfway through the series). The appearance changes, the gender changes—on this side of the fourth wall it’s continuity issues and a writer who decided, near the end of the game, that she wanted Spot to be female instead of male—but in the Trek universe, pretty much every being is infinitely mutable. Alien invaders, viruses, strange manifestations of space and time, can change a being’s appearance, gender, even species.
Maybe Spot is a shapeshifter. Maybe there are multiple Spots. Spot 1.0 the long-haired ginger, Spot 2.0 the ginger boy, Spot 3.0 the ginger girl.
They (or he, or she) are Data’s emotional rock. Long before he has the chip that allows him to feel what humans feel, he understands that Spot is his friend. Spot is there, quietly in the background, when he comes to new understandings about human life and human nature. When he’s had a rough day or week or year, he comes back to Spot. From Spot, more than from any other being, he learns how to love.[end-mark]
