Aug. 8 (UPI) -- A man was spotted riding a train in Massachusetts while holding his pet snake on Monday afternoon.
"Snake. On the train," she wrote. "MBTA uh...what's the policy here?"
The MBTA responded to Keane's inquiry and asked her to provide details about the train ride before clarifying the snake was not permitted to be handled out in the open during the ride.
"During peak hours, small domestic animals must be kept in a lap-sized carrier," the MBTA said.
Keane told WHDH other passengers were intrigued by the snake, but she wasn't a fan of the unusual pet.
"It was gross," she said. "This was probably the weirdest thing I've seen on the train."
The MBTA reminded passengers of its pet regulations and Keane said she hopes it will be the last time she shares a ride with a snake.
"I don't want to see snakes on a train. I don't want to see snakes on a plane," she said.
