Thanks everyone for the kind words and good suggestions. Jasper has now been missing three weeks...
Took my two boys all around the area several times, shaking his treat can too. Jasper loves to follow the dogs and me around, so if he was anywhere in the area he would have come to us. He was always rubbing and loving on the dogs. Although he wasn't outside all the time, he did love to hang out on my front porch. If he was out when I came home he would run up to my car to greet me. By the time the sun set he was snoozing on my bed. I often couldn't tell which was my purse or Jasper on my bed in the dark. Always slept with me at night, laying next to me as long as I was quiet. Had to have a paw or something touching me. Miss him terribly. My daughter came over and gave me a gift to help, meaning well...a black and white stuffed kitty...and I disolved in tears instead. Just not the same. I'm not ready to stop looking. Getting to be a nut about him being missing, pictures on my dresser, his catnip mouse next to them. If you're not a cat or dog person, you wouldn't understand.
