Protagonists were Sally and Jim, ages 11 and 12 or thereabouts ("Jim, six and a half, and Sally, six" in Martian years) middle-class white suburban kids whose family moves to a Martian dome-city.

Previous colonists believe the highest Martian life-form is a three-eyed tortoise (possibly with some discussion of how Earthly animals' pituitary glands evolved from third eyes), but Jim and Sally discover a cute Martian cat and humanoid Old Martians. Illustrations include said animals, the dome city, caterpillar-tread domed rovers.

Probably from the 50s or 60s, early 70s at the latest? Paperback cover possibly yellow.

  • I think I remember this book; if so, I got it from a BookMobile around 1974 in the US. I don't recall much more about it, except I think I remember that the city domes were made of plastic? (which isn't hugely important; I'm not sure why I'd remember such a trivial thing)

Found it. Lost Race of Mars, by Robert Silverberg. Definitely the book I was remembering, and it involves Martian 'kittens', and the character names are right.

  • Whoa! And here I thought I didn't get around to Silverberg till the 90s. Commented Oct 20, 2015 at 21:28
  • Same here! Never would have connected him with this book.
