Tabby Cats Extension is a free Chrome add-on developed by Alissa Chimienti. This extension allows users to add their own virtual cat to every webpage they visit. By creating a cat on MyTabbyCats.com and installing this extension, users can enjoy the company of their virtual pet as they work, shop, or complete any daily task.

The cat appears in the bottom corner of each webpage and users can buy accessories to customize their cat and showcase their personality. The extension also offers the option to earn coins by creating an account on MyTabbyCats.com. However, it is important to note that users who create an account after installing the extension will not receive the 200 coins. They can contact the developer via email at to have the coins added to their account.

In the latest update 1.2, the size of the extension has been significantly reduced. Additionally, the cat now appears in the bottom right corner of the screen to avoid obstructing any important buttons in the top right. Overall, Tabby Cats Extension provides a fun and customizable way to personalize your browsing experience with a virtual pet companion.
