I just discovered the greatest library book ever (and Helen likes it too).
There Are Cats in This Book
by Viviane Schwarz
Who wouldn't love a book with cats... and yarn. The yarn is my favorite.
The best part is when one of the cats asks you to throw him some yarn - and you do - and he says, "Oof!" because it is such a huge ball of yarn.
If you like cats (and love yarn) you should read this book (to a kiddo - but it is ok to just read it without the kiddo... because it is great... but kiddos really like it too).
