My 13 year old black cat has been gone since Sunday night Sept. 27 around 10:30pm. His habits are VERY predictable and though he likes to be out at night he hardly wanders away from the porch (house is set back from the street).He has lived his whole life in this house (Morocco Dr. between Charmian and Boas in Rincon Valley, Santa Rosa). I have placed ads and posted on Petfinders and Stray Pet network; any other ideas? He is the best cat in the world, I am grief-stricken. Thanks, community.
