A cat's tail up may mean a variety of things including: feeling excited, agitated, alert, uneasy, marking territory and showing welcome. It is important to observe the cat's other body language to determine its intentions. An erect and loose tail is usually a good sign that the cat is happy; a taut tail may be a bad sign that the cat is feeling restless or angry.
1. Feeling happy
When a cat is happy, its tail may stand up. This may be because it is playing, being petted or receiving food. If the cat's tail is erect and loose, this is usually a good sign.
2. Anger and Nervousness Sometimes a cat's tail may be raised to indicate that it is angry or nervous. If a cat's tail is erect and tense, this can be a bad sign. It may indicate that the cat is facing a threat or feeling uneasy.
3. Pay attention to your surroundings When a cat's tail is erect, it may be paying attention to what is going on around it. This may be because it has discovered a new sound or smell, or because it is tracking a moving object.
4. Craving things If the cat's tail is erect and curved, this may indicate that it is craving something. This could be food, water or an opportunity to play.
5. Marking territory When a cat's tail is erect, it may be marking territory. A cat releases scent by waving its tail to mark its area. If the cat's tail is erect and waving, it may be because it is marking its body or objects around it.
6. Showing Welcome When a cat's tail is up and wagging, it may be a sign of welcome. The cat may be doing this to show you that it is friendly, or it may be inviting you to play. This could be a good sign that the cat is friendly to you.
