Pet Society is an internet social game developed by Playfish. The game which is launched within Facebook has been ranked as the most popular Facebook application. Players can choose a pet, choose the sex, the name, the colour, the features (ears, nose, mouth etc.), and even visit friends and bring gifts for them. The pet has to be fed, washed and made happy by visiting friends, caressing him and playing with him. The more you play, the more your experience points grow and so more items become available for your pet and your house gains more and more rooms. Of course, you can decorate your rooms with the things you buy in shops.
