Cats, like dogs, communicate a variety of messages using body language, including tail movement. While cats don’t typically wag their tails like dogs, they do move their tails in different ways to reflect different moods. When a cat is relaxed and comfortable, they will move their tail in slow, wide, sweeping moves like Tuna is doing in this animation. Sarah the Pet Sitter knows that different pets have different needs and communicate in different ways, that’s why we always try to observe a pet as much as we interact with them. They have a lot to tell us, from their heads down to their tails.
