Big cities see a variety of commuters take to the subways every day, but Boston may have had the cutest rider yet when a certain furry friend took the T.

Saturday morning, the Massachusetts Bay Transportation Authority Transit Police tweeted a photo of a rabbit riding on a seat in a train on the city's Blue Line.

The only problem — the rabbit was riding outside of its carrier.

"Please keep your rabbits inside their carrier while traveling on the T. Thank you," the MBTA tweeted, adding a thumbs up emoji.

Just to review, rabbits on the T: totally fine, as long as they're in their carrier.

Ride on, my furry friends.
