My Sasha LOVES milk rings! She has quite a stash as the neighbors even save them for her! She can put her little face in the container that they are in and she pulls one out, drops it on the floor, and starts to play! She will throw it in the air and chase it when it rolls. Her favorite game though, is "kitty hockey". She loves for me to slide the milk rings across the linoleum floor so that she can chase after them! It is a game we play almost every night! Tabitha is 17, and doesn't play much anymore. She does occasionally enjoy a milk ring. And she loves to snuggle with any toy that has catnip in it!
