That was just horrible!! Poor little thing, you can just see the look in his eyes and face. See him talking, begging for help. Somebody did film that, watch again, you can see the porch light go on and you can see the camera zoom in. I hope that cat comes back and makes his yard a litter box and slaps the person HARD in the face.
There has been trouble in our community with coyotes. They not only attack domesticated animals but have been attacking small children in their own yards in broad daylight!! I do not worry so much during the day but I am at the door with the back lights on when the dogs go out to potty. I keep a broom and a baseball bat right there. If something bothers my pets, I will protect them. I don't have many wild animals come into the yard now. I have a 88# chow that can do the job if need be.
