I have been playing this game over the last few days and initially, found it great. You have your own house with attached vet clinic and you greet your customers and diagnose their pets. You can then keep their pet at your clinic and deliver whatever medicines etc it needs each day until it is cured. If you succeed you are paid and your reputation is raised etc. If you don't, customers threaten to tell all their friends you are useless.
You also cook meals for your sim on the cooker which can be tricky but it's something else to do within the game.
Over a couple of days of play I've treated cats and dogs for things like flu (give it medicine)and fleas (wash it in flea shampoo) and EXPECTED this game to progress to more exciting things but having read previous reviews, it doesn't look like this is going to happen! The game has told me a few times I have had a 'promotion' as a vet, another thing that made me think the game would progress to bigger and better things but it doesn't seem so.
For small children however, the activities like washing pets, brushing them, chasing them with a stethoscope etc might be great fun.
It is a game with such potential, how about a variety of animal types, or more exciting treatments? Wasted.
I thought it might progress once I had enough 'simoleons' to buy a larger house/clinic but no. I have found the layout hard to navigate around and fitting furniture where u want it is a nightmare. For instance the kennels in which you house all the animals are too huge to fit where you want them, so if you want more than one to improve your business it's difficult.
I must stress that I've only played with this for a few days, but it seems very disappointing. I loved Sims2, and the Sims2 castaway wasn't bad but this is very different. If you are after a pets game get something totally different.
