The feline was spotted by a resident in an apartment overlooking the site at 75 Alford Avenue in Charlestown, who contacted the Animal Rescue League of Boston’s Field Services Department.

Officials from Boston’s Park and Recreation Department helped the league’s rescue team gain access to the site and set up traps.

“It took two days, and in the end, the kitten overcame her fear and gave in to her hunger,” the rescue league said in a statement. “She emerged from underneath the shipping container and into an awaiting humane cat trap.”

The kitten, now named Ally, was brought to the league’s Animal Care & Adoption Center to receive veterinary care. She is in good health and is friendly but undersocialised, the statement said.

Ally will likely be available for adoption soon.
