How do they work?

Displayed in your profile is your cat nip. Everytime you post, you gain a few cat nip. Now, you can spend them on the shops here. Only admins can create shops. At the bottom of every shop you may order. Example of order;

I, (Username), Would Like To Purchase A (Name Of Purchase).

Add extras in orders if the purchase requires extra text.
Once you purchase them, points are deducted from your account, and the item shall be PMed to you. Its as simple as that!
