Try it with TWO cats!!! LOl Yes, I make a ball of yarn for them to play with. It doesn't stop them from trying to get to my yarn but it slows them down.
HINT: When make an afghan that requires that many chains.....every 50 chains, put a tiny gold safety pin in the chain....at 50th chain, 100th chain, etc. it sure beats having to count and recount so many!!!
