Only about thirty of more than two thousand species of animals inhabiting our planet have been domesticated. Domestic animals are not only pets that live in our apartments and houses and are good friends of ours. This group also includes cattle that live on farms and bring benefits to people. Poultry such as chickens, turkeys, and ducks are sometimes regarded as pets, too.
When it comes to domestic animals, most people have their pets in mind – cats, lap dogs, hamsters, turtles, parrots and so on. These animals are usually useless, and people keep them just for their own pleasure. Sometimes people opt for more exotic animals - rats, ferrets, and even reptiles, as well as small crocodiles. However, in my opinion, it is not a good idea to keep snakes at home. Chances are you will never be treated like a friend by them, not to mention that they are dangerous, too. As for me, the only pet I have is a white Angora cat. She's very fluffy. I brought her home when she was only two months old. Back then it was a small and playful kitten. Now she has turned into a full–fledged five-year-old cat, who spends most of the day lying on the couch.
Apart from domestic animals, another category of pets exists. It includes animals that are kept on farms or in paddocks and benefit people. This is expressed in the form of food and non-dietary products (milk, meat, eggs, wool, feather, etc.) or in the form of labor (transportation of cargo, ploughing or hunting, as far as hounds are concerned). Of course, these animals are more suited for the countryside, and not for the city. In Austria, farmers usually breed animals such as cows, sheep, pigs, goats and horses. But in other countries people keep camels, elephants, yaks, and donkeys as pets.
