Synopsis
Because they were so likable and intelligent and adaptable —they were vastly dangerous!
History
First publication: Galaxy, October 1952
Review
Very short, but a good example of this form, if a little predictable. The science is old, with the idea of the asteroids being from an extinct planet. The idea of mammalian creatures that can live for thousands of years and without any air or food is quite a stretch. But if you ignore scientific reality and read the story as more science fantasy, it is enjoyable and sort of funny, which was typical of Galaxy magazine under Herbert Gold’s editorship.
