Kristta...you have a full house, indeed. A month ago I adopted a new cat (a year and a half old) and I think something must be happening when I'm not there because my dog Bella falls over exhausted at night (which didn't happen previous to the arrival of Larry the cat) and I keep find my computer keyboard on the floor or other odd places ("no one knows you're a dog on the Internet"). Maybe it is better not to know what they are doing.
