My kitties love their toys. Sophie goes for the lifelike mouse toys that are filled with catnip, while Lucy prefers the sparkly ones (especially the blue one).
A couple of years ago I got tired of the toys being strewn about the house, so I bought this little basket & put the toys in there. While they're never very good about putting the toys back in the basket, the girls definitely know where they are stored. Periodically I see them digging around for their favorites.
