I am wondering, if anyone else has noticed, their cats tail going up when happy and down when anxious or upset? For example, when it is feeding time, both of our cat's tails go straight up. I take this as a happy mood. Or, when they are told to stop doing a naughty act, like scratching the woodwork, their tail goes way down. Do you think cats communicate with their tails their emotions? Well, I think most of us can not help but notice what happens to their tail when something takes them by surprise or they are in defense mode. lol It always amazes me just how big and puffy their tail can get in just a split second. I think it is similar to when we get goosebumps!
