Why now? My Caturday file for tomorrow already has 42 images in it. (EDIT: thats' just the cats) I always worried that I wouldn't be able to find enough great stuff for it, but the problem is turning out to be that there's almost too much.
You guys should submit some Caturday signs to use. You know, something funny with a cat in it that says CATURDAY. That way, it's easy to see the post and find the cut link. Something like this, or this, or this. But by you! Do it! Leave it in the comments.
