Most of these perks can be accessed from your TCS tool bar at the top of your open window.
Click your control panel (CP) for avatars and signatures. Further to the right, you will find Your Cats, where you can add your kitties profiles and photos that will show to the right of your username.
If I can help you further with this, please don't hesitate to send a private message to my username...
I will get back to you asap.
