Do you know your cat?

If you cat is running with it's tail straight up, ears perked--it's happy and anticipating something pleasant. Sometimes they will flick or bend the tail, but once again, the angle of the ears & whether the fur is held sleek on the tail is an additional indicator. If the fur is bushed out and the tail is crooked, particular if the ears are held back on held flat on the head, kitty is anxious about something.
