Cat Shows Dominance Over Dad

My husband Nick and my cat Carrot are always fighting for dominance in the house. All windows in house are accessible to Carrot but we keep the shutters in the living room closed so the dogs don’t bark at everything they see. In the video, you see Carrot opening the shutters to birdwatch. Nick quickly closes them, Carrot is not going to have it,so he continuously opens them back up, while my husband continues to close them, calling him a bastard. Finally, after Carrot throws out a spiteful death stare at my husband Nick, he once more opens the shutters,then goes to open a second set of shutters, knowing that my husband cannot reach this set of shutters. 1 point for Carrot, 0 for dad.
