The Little Pets of Arkkhan

In Short

This science fiction tale from 1947 follows the crew of the Star Climber, a ship of exiles serving a sentence of isolation from Earth. After touching mysterious, fur-covered organisms on a desolate asteroid, the crew members are colonized by parasitic entities that feed on human thought. The story explores the harrowing struggle to retain one’s identity against a superior mental predator. It has endured as a classic of the "pulp" era, capturing a specific mid-century anxiety about lost autonomy, the crushing weight of loneliness, and the unexpected antidotes to corruption.

The Story

Kent Knight, a man serving an exile sentence far from his home planet, touches a soft, fur-covered creature he finds on a barren asteroid. Almost immediately, a parasitic entity from the race of Arkkhans burrows into his mind. The parasite, or "Thing," grants Knight an artificial, intoxicating sense of peace while systematically stripping away his will. The entity intends to use the Star Climber as a vessel to return to Earth, where the Arkkhans plan to enslave humanity by occupying the minds of the population.

Knight experiences horrific mental agony as he attempts to resist the entity’s control. He discovers that his shipmate, Sammy—a man who stays in a constant state of heavy intoxication—remains strangely resilient. As the Star Climber unknowingly drifts too close to the Earth exclusion zone, it is intercepted by a Space Patrol ship commanded by Bob Mallory, an old rival of Knight’s who is also the man now loved by the woman Knight left behind. The Arkkhans attempt to seize Mallory and his crew, treating them as fresh hosts.

Knight, realizing that his own suffering has acted as a kind of vaccination, gains the ability to fight back. He discovers that the parasites possess a physical, albeit ephemeral, nature that reacts violently to strong alcohol. By forcing the ship’s crew to consume Sammy’s moonshine, Knight and Mallory trigger a "purge" that kills the parasites. The entities dissipate into shadows and vanish. In the aftermath, the crew is rescued, the threat to Earth is neutralized, and Knight finds peace in the knowledge that his rival, Mallory, is not as settled in his own life as he once seemed.

How It Unfolds

The encounter Kent Knight discovers a small, furry creature on a bleak asteroid and impulsively touches it, unknowingly inviting a parasite into his psyche. The entity begins to exert control, initially offering false comfort before revealing its intent to use the crew as carriers.

The internal war Knight endures waves of agonizing pain as he fights to maintain his individuality against the entity’s commands. He realizes that others on his ship have also been infected, including the Captain, who has been manipulated into believing the asteroid’s water is a fountain of youth.

The intervention The Star Climber triggers a warning from a Space Patrol ship after crossing the forbidden line near Earth. Knight uses a coded left-handed salute to warn the incoming commander of danger, hoping to prevent the parasites from spreading to the patrol ship.

The realization Knight observes that Sammy’s constant state of drunkenness has inadvertently protected him from total mental takeover. Recognizing this, Knight and Mallory orchestrate a ship-wide "purge" using alcohol to kill the parasites living within the crew.

The aftermath The parasites are destroyed, leaving the crew dazed but human once more. Knight and Mallory reconcile their past differences, and the Star Climber prepares to return to the civilization it nearly jeopardized.

The People

Kent Knight is the protagonist, a man defined by his deep-seated fear of pain and his lingering love for Mary Jo. His journey is one of endurance; he begins as a man broken by exile and ends as a victor who chooses the reality of pain over the artificial peace offered by the Arkkhans.

Sammy serves as the unlikely key to survival. Though he is an alcoholic attempting to drown his sorrows and his fear of "something" trying to steal his soul, his persistent state of intoxication renders him an inhospitable host for the Arkkhans.

Bob Mallory is the "lightning" to Knight’s "slow-burning flame." As an Space Patrol commander and Knight’s romantic rival, he represents the life Knight lost. He ends the story humbled, realizing that his own life is not the perfection he once imagined.

The Arkkhans (or "Things") are the antagonists. They are parasitic, bodiless entities that seek to conquer Earth by hijacking the minds of the powerful and the desperate. They view humans as "weak creatures" meant to be their hosts.

In Its Own Voice

"Tender and soothing as a wind-wafted melody in the first hush of evening, his grateful mind whispered. Then his mind was screaming as the spider thread grew jagged edges that clawed open the first pain wounds and tore them wider."

Knight describes the deceptive nature of the parasite, which begins with comfort before turning to visceral agony.

"Yes, I know you know my every thought, Thing! You've stolen my mind. But you cannot steal me. I am Kent Knight. I am a man. You, Thing, are my enemy and man's enemy."

Even when his body is no longer his own, Knight asserts his identity to maintain a psychological distance from the occupant.

What It's Really About

At its core, this book is a meditation on the sanctity of the human mind and the struggle to remain an individual in the face of forces that promise easy happiness. The parasites represent the seductive nature of total surrender—the desire to stop fighting and simply "be happy." Knight’s argument is that identity is defined by the ability to feel and process pain. By rejecting the "peace" offered by the Arkkhans, he chooses the messy, difficult, and genuine experience of being human. The story posits that while we may be vulnerable to outside influences, our capacity to suffer for our own values is ultimately what prevents us from being fully consumed by those who would use us.

Why Read It Today

Readers who enjoy mid-century science fiction will appreciate the urgency and the sharp, punchy prose of the era. The book is short, fast-paced, and rarely dwells on technical exposition, focusing instead on the psychological tension of the "mind-invasion" trope. It carries the distinct flavor of 1940s pulp fiction—bold, direct, and slightly melodramatic—which makes for a quick and engaging read.

However, modern readers should be prepared for the period-typical attitudes regarding gender and social roles; the characters’ dynamics are firmly rooted in the tropes of 1940s space operas. The concept of alcohol as a "cure" for alien possession is a strange, lighthearted touch that contrasts sharply with the grim, agonizing descriptions of the mental parasites. This juxtaposition is the book’s most memorable trait: it is a story that balances the existential horror of losing one's consciousness with a strangely pragmatic, blue-collar solution. It lingers in the mind because of that strange mix—the "furry little butterballs" that turn out to be the ultimate threat, and the hero who kisses his friend’s bald head in a moment of intoxicated relief. It is a snapshot of how a different generation imagined the battle for the soul.
