Cat Refuses to Let Dog Go Outside

Check out the moment that Macy the cat refuses to let her sister Lady the Retriever/Lab go outside.
Lady loves the cat but is absolutely terrified of her despite her sizeable weight advantage. On the other hand, Macy has a significant dislike for the dog and loves to torment her at every opportunity.
Here, Lady wants to come outside to see her Mum and Dad. Despite much encourage, Macy takes great pleasure in blocking her path so the dog can not exit. There’s plenty of room for the dog to get past but her fear of the cat prevents her from doing so. The dog made it outside eventually but only after the cat has decided to move on!
