They are animals that have learned to appreciate the companionship of humans as normal. Domestic animals are the animals that can also live with humans but they do not offer the same type of love and affection that pets give.
Domestic animals are normally tame but they do not usually crave human companionship the same way that pets do. Some examples of domestic animals are chickens, cows, and goats.
