Our hairless dude is very fussy about cat toys, as in he rarely likes them BUT he LOVES these wool balls. We play fetch and "goalie" and avoid mainstream plastic pet toys as much as possible. We don't worry about him injesting toxic subtance through his mouth with these. The tin is helpful too, both for finding the balls and for keeping Lucien from attacking and mangling them, a favorite pastime of his. I've included a picture of his crazy excited cat eyes/what he looks like when we get ready to play "goalie" and I'm getting ready to "kick" the ball with my finger and a video of him chasing it. Maybe your kitty will love these too!
