How to Download the Petz 4 Game
Since Petz is such an old game, it is difficult to get new people to play. My hope is that by sharing where to install the game here, that more people will find the game and join the "petz community" of petz players both old and young (there are people in their 30's and older that still play the game. I'm serious.) In addition, since the game is so old it's very hard to obtain. Ubisoft no longer sells the game, and when it was around they even had a patch & demo available where it could be obtained for free, so there should be no issue with me including it here. I have not uploaded the files myself, but am simply pointing you in the right direction of where to find them.
Note: Unlike Petz 4, there does not seem to be any legal way to download Petz 5 for free. So I probably would stick with this version if you decide to play. Petz 5 also seems to be a bit glitchy and is not backwards compatible. Since most users on the web use Petz 4, I would advise this one simply because if you want to adopt petz out to other players, you will be able to reach a larger audience by making them available to all people. Even those who own Petz 3 can adopt petz from Petz 4. Yay game compatibility!
Should work on all "Windows" computers, but if you want to play on a Mac... I personally don't know how to make that work.
Save into "My Documents" in order to save some trouble with issues about where petz are saved and maintaining your game's data.
NOTE: If playing on Windows 10, do NOT "enable PetzA profiles" in the "PetzA options" or you will have to reinstall. I will update this later if I find out a wayto make PetzA profiles compatible with older versions of windows. Otherwise, it sounds like Petz is working with Windows 10 (and all older versions).
How to install:
STEP 1: Download the petz demo here and save into "My Documents" (NOT program files)
(there seems to be some issues with newer computers when installing into program files and this prevents many issues)
STEP 2: Patch the game with "PetzA" from Sherlock Software to make it the full version of the game
STEP 2: Open Petz. Enjoy! Head over to the "adopt" page or any of the "apply" pages, let me know you're new and I'll shower you with petz. ;)
