My older cats love fishing rod toys, and the catnip bags from CPL shops - the bags aren't very interactive, but are very popular! Astryd, the wee one likes to play fetch - a lot! We tie an emtpy crisp packet in a bow and she'll spend about an hour running after it and then bringing it back and dropping it on the sofa for us to throw again. When she's bored of playing with us she just picks it up in her mouth and carries it to another room to bat about and beat up!
