Blowin' up: Meet the 5 fastest-growing Facebook games

It might be hard to admit, but as some point, you'll probably fall victim to FarmVille fatigue. Symptoms include checking in on your game less than once a day or plowing your fields, then finding you're too tired to plant new seeds for the next round of crops. If this sounds familiar, we have the perfect solution -- spend some time checking out these five up-and-coming Facebook games and see if they're worthy of your regular rotation.

Happy Pets
This pet simulation game on Facebook lets you adopt and take care of adorable kittens, feeding them, playing games with them and then, when they're all grown up, give them to a loving family in exchange for cash. Then the process starts all over again. It's a little more of a realistic pet game, than, say, Pet Society, where you can dress your pet in costumes and take it fishing.

Pros: Playing with these adorable kittens is like virtual Prozac.

Cons: The kittens grow up to be cats, which are not as cute. Also, if you don't like cats, you're SOL for now -- puppies are "coming soon."
