Joe - The photos of Katie are wonderful - what a beautiful girl she is! Our two scalawags love playing "hockey" with the tops of Gatoraid bottles back and forth across the kitchen linoleum, especially at night when we're sleeping and they aren't. Another favorite pastime is to roll pill bottles from the pharmacy across the floor just to listen to the sound of the pills rattling inside. Ian has fastened the lids on with tape so they won't accidently come open and cause problems with spillage if the cats get at them. He fashioned some pill bottles with a few coins inside which the kat kids simply love to roll and listen to, also. If it makes noise and pesters the dickens out of the humans in the house, so much the better. And you need to be especially careful walking around our apartment - you might get run down by a "tussleball" of two cats wrestling together and you can't tell where one leaves off and the other begins and they roll all over the apartment, from room to room. It's hilarious to watch as long as they don't bang into you.

I have one, DOG that has a thing for milk bottle rings. He has they hidden everywhere in the place and knows where every one is. My wife will clean and finds piles of them she moves them and he puts them all back where he had they hidden. People who are cat lovers just don't know how they are, each has it own personality and amazing imagination when it comes to finding games to play.
