Origins of our relationships with these animals
To those saying there's no difference between cats and dogs and chickens and cows, you're wrong. As a species we cultivated cows, sheep and chickens (and others) as food stock. We changed them, domesticated them and used them for food and sometimes clothing. Cats and dogs were domesticated for different reasons. We domesticated and changed them as assistants, companions and partners.
