Last spring, my mother was visiting my brother from out of town. She had her ten year old furbaby with her as usual. My brothers family had a cat that attacked Mom's baby while she was there, so Mom was being SO protective and guarding her.
Mom had a Dr's appt at a specialist in town and could not take her baby with her. Brother has a totally fenced in small deck on the back of his house. It sits up, like on a second floor. Mom put her baby on the deck to make sure the cat couldn't get to her before she left for the Dr.
Somehow, Crystal (furbaby) got off that deck. I'm SURE she was searching for Mom.
When Mom got back from the Dr, my SIL was frantic looking for Crystal. She said she was "there one minute and gone the next"
They called and rode and called and rode around the neighborhood, my mother in hysterics and crying. They made signs and put up, asking neighbors about seeing her, etc.
They had just finished talking to a neighbor down the block and were headed up the sidewalk, when they passed a car sitting on the side of the road. Mom looked in the car and there was a little girl in the back seat with Crystal in her lap! The window on the car was down and Mom RAN to the car reached inside and yanked Crystal off the poor little girls lap!
I'm sure the little girl was scared to death of this hysterical woman reaching in the car, but Mom was SO happy to have found her baby.
It seems the little girl had found Crystal as she was getting off the school bus and took her home. The little girls mother recognised that Crystal was well groomed, had on a collar and HAD to belong to someone. So, she had taken the little girl and Crystal through the neighborhood asking about anyone losing a dog.
It was a very happy ending. Mom still visits my brother, but overnight visits are spent at pet friendly motels
I hope you find your baby. I can't imagine anyone seeing him and not taking him in. Hopefully, it's just a matter of time until you and the finder hook up.
