Missing our kitty

Last night sometime between dinner and bedtime, our kitty Dusty slipped out the door somehow. He has been trying to get out a lot lately despite being fixed and an indoor cat for the past year. We put up posters today and are hoping that someone finds him and brings him home to us. Katlyn is the most sad because she considers him her cat. We've gone walking and calling to him several times but I imagine he's hiding from the sun right now. We'll go out again after dinner. I'll keep you posted.
