She called the police, who came and took a look, just before 8 a.m. June 24.
"The head appeared to be torn from the body, and the neck was missing," said Sgt. Kevin Daley.
From the fur, which was disheveled and moist from saliva, police guessed the cat was killed by an animal, rather than any act of human cruelty.
"It wasn't severed or anything like that," said the sergeant, reading the police report. "I guess it was chewed up, so it looked like it was attacked by another animal."
The woman who discovered the cat said it didn't look familiar to the neighborhood, which is Vernona Avenue off Love Lane. It could have been feral, said Daley.
As for the cat's attacker, "my best estimate would be a coyote," he said, citing other possibilities such as a bobcat, mountain lion or even a loose rottweiler.
It's not unusual for animals to attack other animals, he said, but noted this is the first time he's seen an incident like this in more than six years of working in Danville.
