Initially released only in the Canadian App Store, Zynga’s Dream Pethouse has now been released worldwide and made available to everybody at no cost. Available to everybody who has and iPhone or iPad, of course!

The app’s title says most of what you need to know about the game itself: Dream Pethouse gives you a huge tree and your goal is to build the best house for your pets. Like all things in the world, the new pets are delivered to your tree house by storks. However, getting these pets is random and all you need to get more is more rooms. So basically, all you have to do is to keep adding rooms to your Dream Pethouse in a tree and eventually you’ll have tons of different animals living there.

You can even re-live their most important life moments by checking out the photo albums and I am sure you’ll have a great time stuffing your tree with animals.
