Emergency crews responded to a house that was sinking into the East River on Sunday afternoon, officials said.
The three-story, wood-frame house in Throgs Neck in the Bronx was built on pilings which, along with structural beams, had failed, the Department of Buildings said.
The home had partially collapsed in the back, the Buildings Department said.
Neighbors said about 60 cats were being rescued from the house on Schurz Avenue. The people who lived in the home weren't there at the time.
No injuries were reported. The Red Cross was helping two residents relocate, the Buildings Department said.
