Neighbor Mike Lienert found Sugar and called police, claiming the cat was lost and possibly injured.
Speaking with local TV station WFMZ, Lienert gave a chilling account of his interaction with a North Catasauqua police officer.
"The first thing he said at the door, is, 'Well, it's not the most politically correct thing but just so you know, if it's a wounded animal, we're probably going to have to put it down.'"
Not long after that, Lienert says, the officer shot Sugar dead, telling the man he would have to clean up the mess.
The cat was hissing, he adds, but did not seem dangerous.
"I guess he didn't want to make any effort to lure and catch her for us to claim, so he pulled out his shotgun and shot her dead," the cat's owner Tom Newhart wrote on his Facebook page.
