Ok props need to go to the guy who did the original flash file of the cat.

I've taken it - stripped it down, removed sound (as would get really annoying as a screensaver with sound) and converted to a .scr (on request)

you can get it here -> http://www.gnm.org.uk/catlick.php

versions :

.exe (with install/uninstaller)
.zip (compressed .exe)
.scr (for those who are weary of downloading a .exe of an unknwon site)
