my cats love the sound these make. i "marinate" these in catnip, or you can buy them premarinated. either way is a good option. even though the catnip doesn't stick super well to these toys, the cats love the sound of them and the feel. i can't get them away from the kitties. they love them and refuse to give them up. if/when they need to be replaced, i'll be getting them from here as i can't find the larger size any where else. great deal. highly recommended. oh, and btw, i have a siberian (similar in body shape/size/style to a maine coon) so good for big kitties and kittens alike.
can't resist the crinkle
