Kitty Tartan is a site that features tartans that match cat colors. The site is loosely based as a registry although we are just having fun with it.
Tartans generally represent a clan / family / country, etc. Here we have them representing a Kitty or perhaps a Kitty family. Tartans are made from a plaid pattern.
The Kitty Tartan DESKTOP app can be purchased for $4.99 through PayPal and Agency Zen. Agency Zen is the “operational” arm of Dan Zen – mad inventor at http://danzen.com where you can find many such applications.
