Of course, that was precisely why they were dangerous! "I didn't know you killed them," she said venomously. "I won't have to kill many. Besides, they're only animals." " "They are. I told her she had the wrong neutroid, but she got mad. Went and got the sales receipt. It checked with her newt, and it was from Intelligent "Nothing to worry about, is it Terry?" He looked at her peculiarly. "Ever think what might happen if someone started a black market in neutroids?" protested hopelessly, knowing that a logical defense was useless against sentimentality. "Baby—" "Don't call me baby! Call them baby!" O'Reilley's pet shop—right place, wrong number. I just don't get it." The dog was saying, "Don' sell me, Dada. Don' sell me." Norris smiled sardonically to himself. The non-human pets were smarter than the neutroids. A K-108 could speak a dozen words, and a K-99 never got farther than "mamma," "pappa," and "cookie." Anthropos was afraid to make the quasi-humans too intelligent, lest sentimentalists Norris grinned and drove on. A class-C couple, allowed no children of their own, could get quite attached to a cat-Q-5. The felines were emotionally safer than the quasi-human chimp-K series called "neutroids." When a pet neutroid died, a family was broken with grief but most couples could endure the death of a cat-Q or a dog-F. Class-C couples were allowed two lesser units or one neutroid. of growth hormones, trying to raise himself a harem to sell. Besides, something he had been expecting for several days. Attention All District Inspectors: Subject: Deviant Neutroid. You will immediately begin a systematic and thorough survey of all Negligency Case. Seize all animals in this category, impound, and run proper sections of normalcy tests. Watch for mental and glandular The bio-agent waited. Again the thought of a black market troubled him.

If allowed to reach age-set or adulthood, such a deviant could be dangerous to its owner or to others. Hold all seized K-99s who show hundred square miles. Its replacement-quota of new neutroids was around do it in a week? And there were only eleven empty neutroid cages in his "I thought they were all registered," Anne said. Bermuda K-99 serial numbers that had entered his territory, together with the retailers to whom the animals had been sold. A week's deadline for finding and testing forty neutroids would put him in a tight squeeze. Glubbes—called a while ago and said her baby was sick. I must be getting absent-minded, because I forgot she was class C until I got there." He hesitated. "The baby turned out to be a neutroid. It's dying. Eighteenth order virus." "So?" understand?" "I think so," Norris replied slowly. "But what do you want me to do? Can't you send the neutroid to a vet?" "She insists it's going to a hospital. Worst part is that she's heard of the disease. Knows it can be cured with the proper treatment—in humans. Of course, no hospital would play along with her fantasy and take a neutroid, especially since she couldn't pay for its treatment." "I still don't see—" "I thought perhaps you could help me fake a substitution. It's a K-48 even though they look exactly alike, the new one won't recognize her. It'll be spooky." There was a long pause, followed by a sigh. "I'll try it anyway. Can I come get the animal now?" Norris immediately regretted his consent. It bordered on being illegal. But he saw it as a quick way to get rid of an animal that might later citizens with resisting a Federal official—namely me —and charging one of them with assault. I tried to pick up their neutroids for a pound inspection—" Yates bellowed lusty laughter into the phone. "It's not funny. I've got to get those neutroids. It's in connection with the Delmont case." Yates stopped laughing. "Oh. Well, I'll take care of it." "That'll be all right. And listen, Yates—fix it so the charges will be dropped if they cooperate. Don't shake those warrants around unless they just won't listen to reason. But get those neutroids." "Okay, boy. Gotcha." Norris gave him the names and addresses of the three unwilling mothers. "Come on," he grunted. "Let's unload some neutroids, before I forget with a conveyor belt leading from it to a crematory-incinerator. Norris kept the third locked lest his wife see its furnishings. The doll-like neutroids began their mindless chatter as soon as their keepers entered the building. Dozens of blazing blond heads began dancing about their cages. Their bodies thwacked against the wire mesh they appeared completely human, with baby-pink skin, quick little smiles, and cherubic faces. They were sexually neuter and never grew beyond a predetermined age-set which varied for each series. Age-sets were available from one to ten years human equivalent. Once a neutroid reached its age-set, it remained at the set's child-development level until death. "They get to love whoever feeds them." "I can't see—" "How would you feel about disposing of something that loved you?" Anne folded her arms and stared at him. "Planning to dispose of any had a couple of flaws—something wrong in the central nervous system's determinants, and in the glandular makeup. Not a standard neutroid ovum. He passed it on to the incubators to get a credit, knowing it wouldn't be caught until after birth." "So it would develop sexuality. A neutroid would be born a female if they didn't give it suppressive doses of male hormone prenatally. That keeps ovaries from developing and it comes out neuter. But tried to bite, but subsided a little when she disentangled it from the snare. "Kkr-r-reee," it cooed nervously. "Kkr-r-reee!" She looked up and shook her head. "It belongs to somebody else. If it fixes a libido attachment on you, you're actually robbing its owner. They can't love many people at once." She snorted, but installed the thing in its cage. "Anne—" Norris hesitated, hating to approach the subject. "Do "What was it?" "Neutroid trouble." "You meet up with a lot of unpleasantness in this business, don't you?" "Lot of unpleasant emotions tangled up in it," he admitted. out of the north. He went into the neutroid room and flicked a switch. A few sleepy was obvious. Society manufactured them because killing them was permissible. Human babies could not be disposed of when the market became glutted. The neutroids offered solace to childless women, kept them satisfied with a restricted birth rate. And why a restricted that he had damn little chance of being born to enjoy it. A neutroid filled the cradle in his stead. A neutroid that never ate as much, or grew up to be unemployed. A neutroid could be killed if
