placekitten.com, a website by Mark James, was recently created to generate arbitrarily-sized placeholder images… of kittens. To make it available to a wider audience I created the Kittenate! bookmarklet, a small script that replaces the images of virtually any website you’re viewing with images of kittens at the click of a button.
Kittenate! <– Drag this link to your bookmarks toolbar. Clicking it will replace all the images on the webpage you’re viewing with kittens. (Or you may have to right click and select ‘add bookmark’)
