Bernie is a good dog, but I’m finding myself unsure if he should stay in our house… Our 8 year old lab is the most mild mannered dog I’ve ever seen (when it comes to

Question: What do you do with a cat who attacks everything and everyone? Our cat lurks behind furniture and then leaps out at people as they walk by. She never seems serious because she doesn’t bite very hard, but it’s getting annoying. Answer: Picture this: Through a deep silence, the young huntress surveyed her territory.
