Petz: Dogz 2 and Catz 2 are adventure games for the PS2 and Wii, although there are virtual pet versions for the PC, Nintendo DS and Game Boy Advance. In this game you are a dog or cat (depending on which game you have), which you can choose from 40 breeds and then accessorize with clothing. Both games are exactly the same, but with the obvious difference that you are a dog in Dogz and a cat in Catz.
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.
There are also minigames you can play, first with wild animals that have escaped from the Zoo, and after that can be selected from the Minigames menu, and from there can also be played in two-player.
