Bit of trivia about pet hares. Their incisors grow continuously, upper ones wearing lower ones down. If something goes wrong with occlusion of incisors, they grow so long hare cannot eat properly. I have seen one with incisors over four inches long, lower ones almost touching skull above eyes.
Another bit of trivia. Rabbits' hind legs are much shorter than those of hares. Almost all pets are hares.
And on subject of revolting diets, rabbits and hares have to eat their own droppings periodically, to maintain instestinal flora capable of digesting cellulose.
