Why does no one talk about urinary problems / cat's urge to pee when cat's tail shaking / vibrating

Because those two clearly go together with my cat. And he has had it for a couple years now... he's neutered, 3 yr old. I've gone to vet many times now, and I'm still not sure if he's in pain. He sometimes has trouble peeing.. but he gets it all out.. unlike my other cat, who has also gotten urinary problems now... Except that problem disappeared somehow.

What you're describing sounds like a cat trying to spray, which neutered cats don't do (actually spray) as far as I know.  My neutered mail tries to do this all the time...he backs up to a piece of furniture, for example, raises his tail and his rear end quivers.  Just nothing ever comes out, thankfully.

But when he uses the litterbox, urine DOES come out.

Is this what you are talking about?  If not, please explain more what you are needing to know.

I've had neutered males who spayed over territorial issues although I understand neutering does cut down on spraying. Strangely, I had a spayed female who would back up to the refrigerator and wiggle her butt like she was spraying, but nothing ever came out. None of the three had any urinary problems.

Neutered cats certainly CAN and DO spray, if they feel like it :/. Fortunately, they don't feel like spraying as often as an intact cat might. But yeah, that does sound like spraying or, if he doesn't actually pee on stuff, what I call "fake spraying". I have 2 males who fake spray a lot. It's just their funny mannerisms I guess.

Does he have trouble getting pee out when he's in the litterbox? Or are you just going by the fake spraying?

The thing is... my cat vibrates his tail when he has urge to pee. He comes to me, meow, complains, and vibrates his tail, and acts exactly like he has the urge. It takes a while, but I almost always eventually get him to do his business. It seems really difficult for him to go to the litterbox though. He sometimes even holds back, but eventually goes there.

Some cats vibrate and quiver their tail and meow just because they're happy, not because they need to use a litter box or have an urge to pee.

If your cat is doing this in a litter box then you should have the vet check for any urinary issue. What are you feeding your cat? Mane peopel feel that a canned food diet can help prevent most urinary issues.

It's obvious it's mostly because he has the urge to pee, I've seen it for almost his whole life. I've gone to vet a million times now. I've fed them wet food their whole life.

The thing is, most cats who shake their tails like that just do it. . .because. No reason; they just like to shake their tails. I'm sure it goes back to their instinct to mark their territory, etc., but it's just a funny habit now. I mean, you know your cat best so you have the best guess about why he's doing it, but most cats who do it don't do it for a particular reason.

So I guess that's why nobody talks about a cat's urinary problems/urge to pee when it's mentioned, because mostly it doesn't mean that .
