If the cat first sat under the boards, and then ran the zigzag, then what prevented him from stopping the dog at these stages, rather than trying to save the body from the fist? If it was already the fifth cat, the owner should have understood what it was for the cat to end when he saw it on the site. Take the dog into the house/volier/to the bond if his "hunter-predator" words "can’t"and "when I"do not understand or the cat itself to scare up to the dog, right?
It is not necessary to say that you have not had time to catch and take away, to stop the dog you do not need to run after it with an arcana. Just the owner considers such killing of foreign cats to be the norm. Well, I hope another time not a cat will come to them, but a bigger dog or a crazy fox.
