Cat's Tail Vibrates

My desexed female does the tail vibrating thing, often when purring about my ankles, or when she wants special attention , like she's saying to me "Mummy, MUMMY I need to talk to you now ! !" The whole tail quivers from base to tip and is bolt upright when this is happening. She also rubs the scent glands on her face on my legs while her tail is doing this :S SO I always thought it was an attention thing? ? ?

Have experienced the tail vibrating and the smug look on a kitty's face when scratched beneath the chin. Hoping you can explain these things so that we can know and act accordingly when they happen. Thought the kitty to be happy when scratched behind the ears and under the chin!?

My cat does, he also starts 'scratching' his ear when you pet him under his chin.

Well, i feel that the obvious cause for such a vibration is that the subject ... in this case, a cat, is trying to concentrate on a particular object in the vicinity. eg: squirrel or bird. It is interesting to note that some animals like cats, cows, goats, etc. do the same, to concentrate on something in particular. Well, have you ever noticed in Animal Planet, that a dear vibrates it`s tail in a particular fashion, when it could sense some danger/irritation, close to it?. I think that`s the same reason for your cat`s tail vibration...

My cat does that when she is happy and wants it to show

I think they vibrate because they are tensing up like if you made a fist really tight. Thats what they do when they spray as well only they are not tensing up a fist. lol

Our female cat does this normally when she is looking out the window at the squirrels or birds and making her cray squirrel noise. I think all cats scrunch up their face when you scratch under their chin.

I do not really know what causes it and our cat does not do that. So, I've never seen a cat do that before.

I would not have the first clue, but you could ask Jaytech.

nope i dont..coz i dont have any pets..im allergic to hairy animals..but still i would like to know why..can you tell me then...??

awwww thats sweet! the name of your kitty Puff! after Puff the Magic Dragon, or was he a little Puff ball, awwwwwww pictures please. I didn't know their tail vibrates and I don't have a kitty.

You know I have noticed my male neutered cat vibrates his tail a lot. It is during different activities. Sometimes when he is practicing his favorite hobby, looking out the window, his tail will vibrate. There are other times he does it when he's coming out of his litter box. And still there are other times that he will do it if you are playing with him. I have never noticed it to occur when he swishes his tail after obtaining a target, whether in front of him or outside the window. Scrunchy face is the face of immense pleasure and I swear I think at that moment, they think that they have you under their control. :-)

I've had many cats and can only comment through experience with them. I had a male cat that was neutered, and every once in a while he would back up to my wall unit with his tail erect and I would watch his tail vibrate. Even though he was neutered, he was still able to spray (which was what he was doing). As far as the "scrunchy face" goes -- my cat's face gets like this every time I stroke it under the chin. I love the scrunchy face look.
