If you do not play with your monster for about 2 weeks, then it will lose happiness and become sad.
Moshlings are pets for your Moshi Monster and do not grow.
A Moshi is what the monsters are called: "Moshi Monsters". You can not catch a Moshi Monster, you adopt a Moshi Monster when you start your Moshi Monsters account. Choose carefully as you can not change your Moshi Monster once you have verified the account.
If you want to change your monster type, you have to start a new account or if you just want to change the color of your monster you have to be a paid Moshi Member. Whichever monster you chose when you first make your account will be the permanent monster you will have.
You can choose to make your Moshi Monster a boy or a girl. It all depends on the name you choose and how you dress your monster and decorate your room.
