What animal leaves a gut pile?

[JonathanG2013]

I was walking my dog yesterday. She was walking near my neighbors yard. She was smelling by a tree in his yard. I looked and there was a small gut pile and blood beside it. I did not see any hair beside it.

Does anyone know what predator would leave just a gut pile?

Some hawks will

Man.

Or Predator in the Schwarzenegger movie. You might want to get out of there. GET TO DA CHOPPA!
