A cat’s tail is tremendously communicative, thanks to how mobile it is. Cats can do so many moves with their tail: they can raise it up and down, sweep it from side to side, move it slowly or quickly, curl it around us or them, trash and twitch it.
By the way your cat keeps or moves her tail, she is communicating something to you. When her tail is up shaking and she is not spraying but looks like it, it’s a good sign! It means that your cat is extremely happy and very excited to see you. It’s a very friendly greeting that she gives you when you walk in the door at the end of the day or if she greets you when you get out of bed in the morning, or she is just happy to see you around. Watch the cat from the video to see how happy he is and excited to see his owner!
