Found an Orange Cat

Address: Marietta, GA

I found an orange cat with medium—length hair in the Indian Hills neighborhood. He is an adult cat, and may even be an elderly cat. He is extremely thin, and has probably been missing from his home for a while. His legs, which give him a little bit of trouble, have some old mjuris. Call me and he prepared to answer questions to de termine if this is truly your cat.

I lost my camera yesterday. I believe it was left in a car at about 2:30 p.m. on my way to the St. Louis Airport or at the Airport. I would love the camera back.
