What I have noticed with my cats is that when Fatman (my pmsing male) is irritated his tail flicks..umm whats the word....impatiently back and forth and its mostly just the tip of it! I also pay attention to his ears cuz when he is mad they start flicking and going back and I know hes about ready to chew someone out for bugging him. Now my other 2 get this casual wagging to their tails as if they are saying look at how pretty I am haha. I think if you watch your cats ears and eyes youll be able to tell better if its out of aggression or playfulness...
It depends. If it's a quick swishing/flicking of the tail, it's in pounce/play mode. If it's a gentle wagging, swaying back & forth, it's a happy sign, much like when a dog wags it's tail.
speaking only for myself and my interpretations/experiences, tail wag means agitated 90% of the time, and 10% of the time it's associated with playing
i remember a friend (who knows nothing about cats) saw penny's tail wagging and said "oh look! she's wagging her tail that means she's happy!" (as in, dogs wag when they're happy)
i laughed to myself silently
i didn't have enough energy to explain that he was in error
also, ears back plus wagging plus a pissedoff facial expression = watch out
I'm a new "cat person" and one of the first things I learned was that cat tail wagging is WAY different than dog tail wagging.
When my cat plays (should I say on the RARE occasion that she plays) the tip of her tail will "switch" back and forth. And definitely when her ears are back and her pupils are large I know she's in no mood for affection.
But she will wag her WHOLE tail (sometimes) when I'm petting her and she's enjoying it. But I usually find that her tail wagging means she wants to be alone or wants to play.
I see Penny with #2 in the middle row (straight out) quite a bit ....... and #2 in the bottom row a lot ("potentially agressive" - my my - I never knew about that)
Bushy tail also means extremely startled, as most of us know.
The tails in this house are Members Of The Family. Tolly's Tail is used to communicate love and possessiveness. If he is near me his tail is wrapped around a part of me. Or he will walk next to me with his tail pressed against my leg.
Mazy's keeps me in laughter as it is so expressive and responds to every little stimulus in very hilarious ways. She has a funny way of holding it in a hump (see 3rd pic 2nd row) and waving it in all sorts of ways, while being held in that position. Her tail never stops moving.
Jennie's Tail is a very quiet individual.
One of my favorite things to do is to sit quietly and speak to each cat in turn, just to see the tails rattle.
"Mazy" I'll say and just the tip will rattle. Mazy. A bigger rattle. But if I keep on with it, soon I've got a fully lashing wiggling thumping Tail. heehee
Riley's tail is very long and heavy so he almost never lifts it up. Most of the time it drags the ground like a dust mop. If he is slightly irritated he will twitch the end of it a bit. If he's mad he flops the whole thing up and down really hard, lol. He does swish it side to side a bit when he's about to pounce on something.
When Rusty's tail is flying high over her body, almost touching her head, she is happy. If she sees another cat outside, her tail will flick back and forth.
Dusty's tail is deformed and she can't fly it like Rusty. It curves off to the side
