Just my luck. The kittens were "returned to sender." A postal worker heard a lot of swearing and threatening language, so they opened the box. Apparently, kittens are one of those dangerous substances that you can't send by mail. Who knew?
And to make matters worse, the box came back with a new litter of 9 black and white kittens. These colors are not sanctioned by the Rainbow Scrappy Challenge! I hope this doesn't mean that I'll be eliminated from the challenge.
