Here here, owning a pet is a dedication and training your pet takes alot of time and patience, if you behave aggressively towards an animal it is going to learn to protect itself or run and hide, if you train a dog to play rough then how does it asstablish the difference between play and attack? Same with cats, playing with a kitten using your hands and fingers is funny but when the kitten becomes a cat and scratches a childs wriggling hand its called aggression, how does the cat know the child ect was not wanting to play? a very good subject Magik!
