My cat elliot loves to play with crumpled up paper, and those puffballs you use for crafts. It is so cute because he will take the littler ones and pick them up in his mouth and bring them to me XD to see such a fat cat with a tiny little ball in his mouth is hilarious. We dont like him using hte little ones but he always seems to get them somehow O_O I just wish they sold puffballs in a larger size! I got him a toy that was a ball of yellow rabbit fur with wiggly legs attached, and I cut the legs off so he would hav the ball, but it's too fuzzy for him :O Maybe they have larger ones at the art store...
