I'm personally more of a dog person, but everybody knows somebody who's got a reptile. Just in case all of y'all with scaly buddies felt left out, I found these lovely pieces by Scott Johnston from the Golden Book of Zoo Animals published 1962 by Golden Press.
That one with the alligator is a true Kodak moment, I think. And check out that easy, breezy handling of the checked tablecloth? The man was a master. If you want to read more about this particular book, there's a lovely feature on it over at Vintage Kids Books My Kid Loves.
