Aww, I love Lilly! I don't have a cat, but I have crocheted while cat-sitting and oooo buddy were those kitties ever eyeballing my yarn. I let them play with a couple small scrap balls of cotton yarn.
Haha, I do believe that! I don't know, why they like yarn so much, but yes mine go crazy for it, too! (I just have to pay attention that they don't eat it, because that is dangerous <.<)
