Just Cats (de.applicate.android.justcats) on Google Play
This app shows changing cat related images from the Flickr network (http://www.flickr.com). The 'More Cats' button shows more cats from the constantly updating Flickr stream. Click on an image to see a bigger version of the file. Please note: The contents displayed is based on the input of the Flickr users and therefore out of control for the app. Therefore from time to time unrelated images may occur in rare cases.
