Hello to all of you. We have a beautiful boy named Dylan who we rescued from a real He'll hole when he was 10 weeks old. He is now 7 months old and very socialized , took him everywhere with us. he now thinks he doesn't Have to listen to us anymore. He loves people, but will trail one of our cats, whines and nudges her whenever he can. She will not whack him one so it now is a game. We have gotten in his face, grabbed him by the neck, scolded him while in the act and he just looks at us wags his tail like he doesn't take us seriously. Is he just that stubborn????he is great in all other areas but will harass her whenever he can. Thanks in advance. Leaves our other cats totally alone.
