Sliding Cat Cursor for Chrome Extension

Sliding Cat Cursor for Chrome Extension is a tiny Chrome/Edge extension that shows a cutout sliding cat near your cursor when you move the mouse downward. Move upward and the cat fades away.

This open-source GitHub build uses the cutout cat image from the original viral photo. Please verify image rights before commercial redistribution.

Permission Notes

The extension uses storage to save local settings. It uses a content script on webpages so the visual cursor effect can appear automatically. The content script listens only to pointer movement direction and does not inspect page content.

Features

• Appears only when the cursor moves downward
• Fades when the cursor moves upward
• Mirrors direction when moving down-left
• Adjustable cat size
• Adjustable sensitivity
• Simple on/off switch
• No tracking or analytics

Privacy

This extension does not collect, sell, transmit, or share user data.

It stores only local settings such as:

• enabled or disabled state
• cat height
• downward sensitivity

The content script listens only to pointer movement direction so it can show or hide the local cat image. It does not inspect page text, forms, links, cookies, account information, browsing history, or page content.
