Lost & found reptiles & amphibians in Cambridge

Leopard gecko, sandy with brown spots, ~4 inches

I lost my leopard gecko yesterday around 3pm in Cambridge. It's about 4 inches long, sandy yellow with brown spots, and has a bright orange tail tip. It lived in a Zoo Med 20-gallon terrarium with a heat lamp and a clear mesh lid, and it has a tiny white scar on its left front toe plus a crescent-shaped mark on the left shoulder. Last seen near Harvard Square on Massachusetts Avenue, by the T entrance, wandering toward the Cambridge Common—it's really important to me to find him.
