Rebels of the Red Planet by Charles L. Fontenay

Adam and Brute followed Goat Hennessey down the corridor, towering over him like Saint Bernards on the heels of a terrier. They turned into the dining room, a big square room centered with a rude table and chairs, one wall pierced by a fireplace in which a big cauldron steamed over smouldering coals.

The dining room swarmed with a dozen small creatures, human in their pink flesh, more or less human in their twisted bodies. As soon as Goat entered with Adam and Brute in tow, the assemblage set up a high-pitched howling and twittering of anticipation and began beating utensils on the dishes, table and walls.
