Not sure were this goes!:shrug: I've had most my life wild and domesticated cats and dogs. I know only that of domestic animals that leave behind bodies without eatting them. But usually its left as a clawed or chewed up animal. These were very strange presents left in my yard. The rats, several of them have only the neck part missing and one has a big chunk taken out of its head. The birds had only their necks muscles missing. What kind of animal does this?
