Gummitch, a kitten with an IQ of 160--how it was measured, the narrator doesn't say--believes he will transform into a human. The unintelligent, young children, though, will transform into cats. He believes he was born in the folds of a bathrobe, for those are his earliest memories. Gummitch wants to hurry the process along.
The reader feels for Gummitch, but his unreliability is a little odd. On the one hand, he's smart enough to know something of literature--apparently well-read with a deep imagination--but on the other hand, he seems not to understand genetics, accepting the more fantastic explanation over the more likely mundane one. Perhaps this is a critique of the genre, tending to reach for the cooler if less likely scenario--and/or of the religious.
