This is a complete nintendogs ripoff!
The game works like this: someone comes to your house/clinic, says that there is something wrong with his/her cat/dog. You diagnose the pet by using a few tools, then you tell the owners how long it will be to take care of the animal, and when they can come back to pick the animal up. After that, you either give the pet medicine and continue that for a few days until the animal gets well, or you bandage the pet to heal them, and you can put accessories on them and bathe them and feed them. You can also pet the animal in the same way you can do it in nintendogs: using the stylus.
Your sim also has the hunger, bladder, ect. meters but that doesn't do much to save the game. You can cook for your sim, but it's easy to figure out how to do and each of the recipes fills up your sim the same amount as each other. The whole game focuses on your house and the park. You cannot go anywhere. You shop for supplies online. The graphics aren't that great, especially the animals. The animals look ridiculous, especially when they are doing tricks.
The controls for your sim are indirect and annoying. Overall, maxis should be ashamed of themselves for ripping off nintendogs(which I sold to get this game) and for ruining what could have been a great game, if it didn't lack depth.
