From WoC Scans:

It's a short story about the mangaka's many cats. They're so furry and cute!

Attemo Nakutemo Neko no Shippo literally means, "it's a cat's tail whether we meet or not" --it's actually a figure of speech meaning "it doesn't really matter if we meet or not" --but in this case, it's a pun because the manga really is about cats.
