Has anyone got any recommendations for very, very durable cat feather toys? My 10-month old Maine Coon loves anything on a piece of string, but especially feathers. However, he goes for them so energetically that they're destroyed within a day or two. The worrying thing is he actually eats them, string and feathers and all. We're paranoid about not leaving them anywhere he can get at when we're out, but he's still munched his way through every feather toy the petshop offers.
Does anyone have any recommendations for feather toys that are super-durable? Dog toys are tough enough, but they don't have the feathers he likes!
