Last summer, a young tabby cat was spotted roaming the tracks in Kenmore Station. “He was a little kitten hiding by the rubber under the rails,’’ said T trolley operator Karen Ingraham. “We don’t know how he got down there. We tried so many times to rescue him, but he would run away and hide.’’ Passengers on the Green Line began noticing the young cat, and snapping photos like this one, taken by Leah Rodriguez.
