Hi, wonder if anyone else has any experience of this? We got a new cat last year, a rescue. When we got her she was in season so we took her to be neutered straight away. She has always been feisty but she is so friendly too, however she swings her tail violently all the time! I've had many cats over the years and I've never known any of them do this. She will be happy and purring on your lap almost asleep but her tail is going crazy! She looks like a little wild cat. All the stuff I've read says she must be in pain or stressed but she doesn't seem to be! Anyone have any ideas? Thank you!
