"After reviewing the footage, we believe the cat was dead when it was brought to the nest," said Rachel Handel, spokeswoman for the Audubon Society of Western Pennsylvania. "We don't know if it was a pet or feral. It's impossible to know if the cat was killed by the eagle or was a roadkill, but eagles are opportunists and just as apt to take something that's already dead as something that's alive to feed their young."
