Not all mammals are created equal. Though all wonderful creatures, some are more suited to human companionship than others. Cats and dogs are the most common types of pets from this animal class, but there are many more that don't mind our friendship and attention.
A group of scientists established this fact by researching animal temperament and assigning various scores against their subjects' level of friendliness towards humans. The study, published in the journal Frontiers in Veterinary Science, excluded farm animals and of course, cats and dogs. Those that rank above 0 are said to be the best companions for humans.
