How do I get my cats to engage? They used to enjoy playing with a feather on a stick type of toy. Lately they run to the cupboard when I go to get it out, seem excited but then as soon as it's out they just don't engage. I've tried different types of ends (different types of feathers and things), playing with balls, mice etc but they don't engage. But then they're acting like they're restless. I don't know what else to try.
