Destroying unclaimed units is the smallest part of it. Honey, before the evolvotron, before Anthropos went into the mutant-animal business, people used to elect dogcatchers. With its population legally fixed at three hundred million, most of the country had become one big suburb, dotted with community centers and lined with narrow belts of industrial development. The cat-Q-5 took its time about answering. 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. You will immediately begin a systematic and thorough survey of all animals whose serial numbers fall in the Bermuda-K-99 series for birth dates during July 2234. Seize all animals in this category, impound, and run proper sections of normalcy tests. Delmont has confessed to passing only one non-standard unit, but there may be others. This could be a ruse to bring a stop to investigations when one animal is found. 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 the slightest abnormality in the normalcy tests. Its replacement-quota of new neutroids was around three hundred animals a month. He tried to estimate how many of July's influx had been K-99s from Bermuda Factory. And there were only eleven empty neutroid cages in his kennel. He wadded the memo in his pocket, then nosed the truck onto the highway and headed toward Wylo City and the district wholesale offices of Anthropos, Inc. They should be able to give him a list of all July's Bermuda K-99 serial numbers that had entered his territory, together with the retailers to whom the animals had been sold. Of course, no hospital would play along with her fantasy and take a neutroid, especially since she couldn't pay for its treatment." It's a K-48 series, five-year-old, three-year set. You're welcome to it, Doctor, but you can't fake a serial number.
 It is possible one or more of them may become dangerous.
 It is possible one or more of them may become dangerous.  They are female and not neuter.  They are defective. They can only say "mamma", "pappa", and "cookie."  They have Eighteenth order virus.
