He does not have to be skilled to get these guys. They consistently come from same direction and they go after bird feeders near house before visiting feeding stations and then if not already full, coops are visited. Cats even help, they get all riled and Scoob goes over to torment cats (same ones he sleeps with) resulting in him finding oppossum.
Gotta love a dog that will take on a possum! My little rat terrier loves nothing more than a nice angry possum for a bit of fun! Usually comes out bloody at the end, and it's not his blood. He's fierce for his size
