Now i'm really curious about this as everywhere I have read suggests that tail wagging in cats is a warning, but my cat Tuxy virtually wags his tail all the time and has never once shown an ounce of aggression, anxiety, or anything other that a happy cat. the loves to be played with and will instantly roll over when i get in showing his tummy, which I know to be a sign of trust, he loves his belly tickled, he loves cuddles, he loves to sit on my lap and purr.. in most cases wagging his tail at the same time.. so really my question is, can a cat wag their tail if happy, not just because they are mad?
