Lost cat, South 2nd Street, 3090, Waco - male tabby, 2 years old

He can open doors that have handles to push down. He is 2 years old. He is a Tabby cat. He is yellow and cream color. He likes to be outside but inside at night. He is not a cat who fights with other cats. He was raised with 2 dogs. My standard poodle and Happy sleep together. I had him in a pet carrier. When I put him in the shed, I forgot he knew how to open the door. He could have been gone 2 hours before I knew. I am 71 years old and a widow. I love Happy so much. He sleeps with me at night. Please help me find him.
