Words are weird.
Mine likes to be under things or on top of things.
Have you ever accidentally stepped on her tail?
Cats sometimes wag the tip of their tail. If it's when it's purring then I think it's because they are feeling good. But I have seen them wag their tail, when they are readying for a fight with another cat.
But that will get her stepped on! ><
She thinks she's hiding, but the tail gives her away.
Please validate me.
