Alvin and the Chipmunks
Well, technically they are not chipmunk, just common tree squirrel. Pet tree squirrels.
The owner feed them with milk and biscuits. And like kittens, they're always in the mood for playing and fooling around.
When I ask for his permission to take a photo, he said its okay and let them play on the cage. Only after I took several shots he mentions that he usually charge tourist $20 for taking photographs. LOL!
Another shot in the comment.
