So I continued my 9 Sided Mat and front post crocheted when it got to the size I wanted it to. I worked 6 DC rows, throwing in some decreases to make the basket a little tight. I crocheted a chain on my 7th row, to make a hole for the kitties. Now, I plan to change sides and crochet around the chain to start forming the cave. All of the little animals have taken a go standing in it and so far, so good.
