"Love this game! You have to try it!"
Everything, trust me. Especially if you download "Petz A" (it's a must with this game so google it) and you have to go to the petz forums to find out more about the game and how to expand it.
Nothing. You can find ANY type of animal and breed if you actually search for it....trust me there is a ton of stuff out there. And by the way there are horsez!! And you CAN take out a ton of petz at once if you download PETZ A.
I love this game and have been playing it since I was little and I'm almost 18 and still playing. GOOGLE "RKC Petz Forum" or "Petz Community Gathering" and you'll see how far petz has gone...There are hundreds of breeds to download and way more awesome things then ubisoft ever intended for these -original- petz games.
My petz website is http://petz-aholicsanonymous.******** and is a great example really cool petz. Like a dragon dog....go see!
