A virtual pet also known as digital pet, is a pet that's not real, or tangible real life, living pet.
Most virtual pets exist in game consoles or computers, and in reality their behavior and attitude is based on the one their programmer intended it to be. So basically, a virtual pet is a creation usually by a human being who drew it, and gave it emotions and reactions.
You tend to the virtual pet as you would a real pet in which sometimes, you need to pet it, feed it, groom it, or just do the general tasks you would with a real pet. You interact with a virtual pet by medium of a computer mouse, keyboard or game controller.
There are many internet web sites dedicated to the care-taking of virtual pets.
