A parable is defined as "a simple story used to illustrate a moral or spiritual lesson".
Writers love to tell them, and we love to read them (especially ones with sci-fi elements).
Written by Shelly Mayer and beautifully-illustrated by Alex Toth, this never-reprinted story from DC's Adventure Comics #431 (1974) came out during the era when Jack Kirby's Kamandi was being published, which might explain why it's set on the planet "Teyton" rather than a future Earth, despite the fact all the animals, except the Snerls, are obviously Earth creatures!
(Kamandi was set on a near-future Earth where intelligent animals [most in humanoid form] rule the planet.)
Tomorrow...another "lost" story!
