Sony's EyePet is more or less a direct descendent of all those Catz and Dogz games (or should that be gamez?) that surfaced in the mid nineties. Both series were massively popular with gamers who were either unable or unwilling to deal with the expense, responsibility or omnipresent faeces that accompanies real-world pet ownership. In essence, the player used their mouse to interact with a cartoon mutt or feline as they pranced around their computer screen. You fed the animal, groomed it, and teased it with toys.
