Soft, bouncy and fun - good value, but smelly
I've knocked one star off for the strong foam smell, as other reviewers have noted. I didn't think it would be a problem, but my cat was so suspicious of the odour initially that she wouldn't play with them until I'd left them out for a couple of weeks. They bounce fairly well and are nice and light for batting, and they don't hurt if you treat on them. My cat hasn't tried chewing them so I can't comment on durability, but the soft, squishy texture seems to appeal to her. A good value pack.
