If you're going to invest in just one kitty-toy, make it this one. The only way to keep a cat from responding to the bell and chasing after the furry whatzit is storing it in a kitty-proof container.
Generally I find kitty-toys to be an immense waste of time because cats tend to find their own playthings. Not so with this innocuous Hair Ball. I received the first one as a present for the previous feline resident and, long after the catmint stuffing had ceased to attract, the current cat dug it out of hiding and it remains his favourite toy too.
I personally appreciate the lack of pieces that can be chewed off and swallowed, and that it's manufactured in the USA.
