Our kitty is missing :-(

I know with all the bad things in the world that our missing outdoor car is not a major thing, but he's become an important part of our family in the time since he first showed up on our door step, so if you don't mind, shoot up a little prayer that we see him in the morning. The kids don't know yet, and maybe some nice family took him indoors, but apparently there is a coyote roaming around our area, so it could be we've seen the last of our precious white kitty. Mittens has never missed a meal, so the fact that we haven't seen him is suspicious.
