These days many people keep pets as companions and this becomes a new lifestyle. In terms of pros, keeping pets plays an important role in filling the sense of loneliness of people. And also, they protect the owner as well as the property. Cats and dogs, for instance, are one of those animals that help fight depression and entertain their owners. However, animals are the source of some diseases and their medical treatment cost a lot. Some pets need special attention and time for example they should walk them three times a day. In addition, dogs are sometimes reported as disturbance during the night by barking and biting. In my opinion, having a pet is beneficial in dealing with stresses and dealing with modern life.
