Female cat peeing standing up

My five year old female cat pees standing up, tail in the air, and her hind quarters shaking. This started about seven months ago and during this time she take spells of peeing outside the litter box, spraying the wall or door. The litter box is in the utility room that is adjacent to the kitchen and she has four areas in that room that she will use. She has been to the vet many, many times. She's had urine tests done and only one showed traces of blood. There have been ultrasounds, antibiotics, steroid injection, and even cat tranquilizers. For two months she has been on a special cat food that I get at the vets office. She's a mix breed cat, I love her and I pay for her expenses, but my husband is pressuring me to get rid of her. Help!

I need a little more info. The vet couldn't find ANYTHING except blood in the urine? Did s/he run a full urinalysis? A UTI is always a suspect when cats are urinating inappropriately. Blood in the urine points to FLUTD. Has she been spayed? Thank you for helping out your cat in this time of need. A vet should be able to figure this out soon, and then you could put everything behind you and enjoy your kitty's company.

She has been fixed. They did test for bacteria, UTI and they checked for kidney stones. She has a long, strong flow when urinating, and she doesn't leave a lot of small urine clumps in the litter. So the vet ruled out FLUTD. I am wondering if a blood test would help.

Did they check her urine pH? I don't think that a blood test would help because this seems to a urinary issue. Did they do an X-ray of the bladder and urethra? This could also be bladder stones or an anatomical defect. 1CatOverTheLine is also well-informed about feline medical issues, so they might have something to contribute as well.

I'm calling the vet in the morning for an appointment and to talk to him about x-rays. Also, if they can do a more complex urine test. Thanks for the advice.

The action you describe sounds very much like female spraying.  Did you recently make any changes in the household that might make her feel she needs to protect her territory?  This could be as major as a new baby or as minor as something added to the utility room, like shelves for example. 

Sometimes, spraying also happens in response to cats outside - have you noticed any strays that started hanging around in the last seven months? Even if your girl usually stays inside, she is probably aware of any cats who might be wandering on your property. 

I'm not suggesting that this is a behavior problem, rather than a medical issue - just offering you something else to consider.  What did your vet say this morning?  I hope you had a productive appointment.

Does she ever yowl or turn up her bum towards you? She may have been improperly spayed. If even a tiny bit of ovarian tissue is left behind the cat will cycle into heat over and over again. This would include spraying.

Do you run Feliway diffusers in your home?  That might help some.

I know very little, really.  First, since she's undergone ultrasound (primarily, one presumes, as a screening for lesion-initiated Cerebellar Hypoplasia), we can rule out most of the obvious  possibilities as well (Feline Leukemia Virus, Toxoplasmosis, Feline Infectious Peritonitis and / or Lysosomal Storage Diseases). 

Was there, seven months past when this began, any head or ear trauma, or an ear infection, or was she exposed to any very loud noises?  If there are periods of attendant discoordination, head-lolling or nystagmus (i.e. darting eyes when she's at rest), I might think that Feline Vestibular Disease could be to blame, and would certainly ask my Veterinarian if she or he felt that was a possibility worth exploring.  

I'd also ask my vet to make a close examination of her spay procedure, since what Primula has suggested above is entirely true.

I'm afraid I've been of very little help, really.

I have to wait until wednesday for my vet to see her. Sorry for the long post, but I am trying to answer everyones questions.
Mellay has never had any kind of head or body trauma. We adopted her March 2014, she was fixed a few weeks prior to that. She lives in a relaxed, safe, and relativity quiet home.
The only change in her life, October 2015, we got a 10 week old kitten. She ignored the kitten the whole time it was here.
Mellay started urinating outside the box early June 2016, later that month the spraying/standing up to urinate started. Thinking that she could be resentful of the kitten, in October 2016 I finally gave the kitten to a friend who wanted her (she has spoil that kitten).
I did replaced the two previous cat basins. Scrubbing and cleaning every possible area in the house and used a urine spot cleaner. She will be fine for few weeks, then she will go outside the box once or twice a day. The vet prescribes something different, a couple of days later she is better, then it starts all over again. I ended up using a 15 inch tall storage tub, with a large opening on the side as a basin. She's part Mane Coon cat and has long legs. Because she doesn't squat anymore, it was the only thing that keeps her urine in the basin. I thank everyone for all the input you have provided.

My female cat does exactly what you describe outside, and pees normally inside in the litter so I assumed she is spraying outside. Tbh it sounds like the real problem here is your husband

I have a 12 yr old spayed female who has problems with her kidneys she is on meds. She stands up in her litter box I have 2 littler boxes I have 2 cats Ms. Mida is the 12 yr old and Sir Tiger is my 6 yr old who I raised at 14 weeks and feral. Ms. Mida stands in her box and pees sometime it goes over the rim and these are giant cat boxes and she throws the litter out on the floor and there is padding under the litter pans. I have had cats all my life this is the first one that has the problems. What can I do?

D Darlene18 this thread is old. I would start a new thread so that your question gets more attention.
