I have this book! It is really cute. The finger puppet is delicate but doable. Cat fur isn't as feltable as dog fur - I find it is best used as roving in needle felting (there are a few projects in the book). I sent my puppet, along with a "diy kit" of extra cat hair to a friend that works with my husband. He is allergic to cats and always enters our house bellowing "Where are those god forsaken creatures!".
Please post a picture! I didn't grab one of mine - I need to make another. I have more than enough raw material. : )
