Catbook — Facebook for Your Feline
Facebook is a social networking site where you can get in touch (and stay in touch — this being the key) with your friends. I have been amazed at how many long-lost friends I have found through Facebook. People from my elementary school whom I haven’t thought of in over 20 years — but remember fondly nonetheless — are getting in touch with me and letting me know how they turned out. It’s really fun.
Catbook is a Facebook application that lets you enter a profile for your pet and then let him or her make friends with other pets and humans. (Yes, there is also a Dogbook.)
This article explains the application and its history: Facebook with Whiskers
I showed Catbook to my own little feline friend but I confess that she has not shown any interest in the application just yet. Perhaps my explanation was somehow deficient.
