For kath1234, Go the "see inside" bit, then save the cat sprite to your local file! ( to do that, just right click on the cat.) then, on your profile, click on "change" on the picture. then on the file bit, select the kitty cat. it won`t appear animated at first, but when you change it to the cat it will start walking after a few seconds. I hope you like it!
