These dogs are very strong, one "chomp" or "stomp" even in play can leave a cat paralyzed. And, like Justice, once they get in the "zone" of playing or fighting they focus on what it is they are doing. Pain from a cat's claws means nothing to them. WHile they will try to avoid it, once they are concentrating on having fun or killing their prey, the pain won't bother them. Justice is not allowed around the cats at all anymore. She chases things that run & they are too big of a temptaion for her. When she is having her run around the house time, they are either in another room or in their hiding spots.
There's a fine line between genius and insanity. I have erased this line.
