Haha, indeed. XD Trying to get pet hair off a handmade project is near impossible. Maybe they think they're helping by giving some of their fur to keep you warm. Either way, I've gotten used to having cat hair worked into my things. :3
I'm not sure, maybe they do think it is helping? "I made it better Mommy!" Yea I've stopped trying to keep the hair off and decided instead to mostly use yarn the same color as the dog... lol sounds silly but it worked for picking out our rug and couch so why not!
