15 Most Interesting Pets That Have Ever Been Bred

15. Mules and Hinnies

One of the most common and most well known animal hybrids around are mules and hinnies. Both are a combination of horses and donkeys, with the difference between the two being that hinnies are the offspring of female donkeys (called jennies) and male horses (called stallions), while donkeys are the offspring of male donkeys (called jacks) and female horses (called mares). Hinnies are often smaller than mules, with a more oblong head shape and shorter ears. It is not uncommon for natural breeding between horses and donkeys, but when this is done selectively (due to human intervention), it is done for various reasons, the biggest of which are due to behavioral selection. Mules and hinnies exhibit the toughness, stoicism and loyalty of the donkey but not their stubbornness, while inheriting the speed, agility and size of the horse without the aggression. They are often healthier and make better riding animals than their parents, making them excellent barnyard pets.
