Our cats love to play with the plastic ring that comes off of the gallon or half-gallon milk jugs. They will bat and carry them all over the house. (I am almost ashamed to admit it, but we have one couch that is very low to the ground, so that you really can't see under it. When we were moving, and we moved that couch, we counted 29 milk rings under it. Needless to say, we got a pretty good laugh out of that one. ) Saphirah also loves Q-tips. She will also play fetch. She brings a milk ring or Q-tip, drops it in front of us, and waits for us to toss it. She brings it back, and we do this over and over until she decides the game is finished.
