Petz: Dogz 2 and Catz 2

Dogz is an adventure game for the PS2 and Wii, although there is a virtual pet version for the PC and Nintendo DS. In this game you are a dog, which you can choose from 40 breeds and then accessorize with clothing. The console version of Catz is the same as this game, except with cats instead of dogs.

You live on an island entirely populated by dogs. One of the reasons why this game is similar to The Dog Island. The main storyline is that you and your friend are tricked into giving a Magic Hat, which is used to keep peace on the island, to an evil wolf named Ivlet. He uses it to destroy the Island, also turning all animals evil and destroying many of the buildings.

Your goal is to repair all the damage you have done, by helping out all the troubled dogs, and finally defeat Ivlet to try and get the Magic Hat back.
