A couple of years ago a Pet Talker (I forget who it was) was moving and she posted a picture of where her refrigerator had been. It made me laugh out loud because there had to be about 20 or more milk jug rings there!! I love to periodically move out furniture. It is amazing what you can find underneath things that aren't even really cat toys but just things that the kitties turn into toys (probably late at night when they are bored!)
