Ernest Lungaro of the Westchester County SPCA said Friday that tests on three cats revealed blunt trauma to the head.
He said a baseball bat, two shovels and a metal pipe were found near the scene in Yonkers. Some of the cats were just skeletons and some had been dead for only three days. A city cleanup crew found them Thursday.
Lungaro said there has been some tension in the neighborhood over feeding stations some residents set up for a large population of feral cats.
The SPCA and Yonkers police are investigating. Lungaro said it was too soon to say there's a suspect.
