I came to the conclusion a cats tail behavior is an evolved anti-predation behavior. We think of this as "I can see the gears in my cats head turning based on its tail behavior". The wider a cats "field of attention" the slower the tail moves, ie: sitting calmly taking in the entire room so the chance for predators to approach undetected is low and hence the tail is nearly idle. The narrower the cats attention the more the more tail moves. Cat is focused on navigating obstacles to get to a coveted perch in the room, tail wags at a medium pace as only half of the room is under observation as it charts a path across furniture to the goal. Cat is stalking another animal with intent focus on attacking, the tail is in its most agitated state and hence will draw out undetected predators to the tail rather than the rest of the cat.I realized this after watching a kitten that was unable to resist attacking our other cats tails when the older cats were focused on something. Wagging of the tail draws out any other predators that may be stalking the cat itself when its attention becomes highly focused, such as when hunting prey.
