Onsior for cat with Urinary Frequency

Hi All-

My 9 month old kitten started exhibiting signs of urinary frequency with little output each time. At one point, he was in litter box 8 times in 30 minutes. I took him to my vet. He suggested it was more likely due to FUC(feline urinary cystitis) rather than an infection. Haze's bladder was too small to do a cystocentesis so I left him there from 10:30a to 5pm in the hopes that he would be able to give a sample. When I returned, Haze had not urinated...at all! The vet did an X-ray of his bladder to be sure of no blockage and everything was clear. He sent me home Onsior a medication that is a NSAID. He said it would help with the bladder inflammation. Everything I read is that it's usuallly for post operative orthopedic pets. Does anyone have any experience with this drug for urinary symptoms?

Of course, as soon as I brought Haze home, he urinated. Murphy's Law every time. The vet said to still bring him back Monday to stay all day so he can check his urine to be sure.

I'm just baffled that Haze had so much urgency to go at home and even whimpered at points and then nothing at the vet.

It's curious because it sounded like he had a blockage or infection.  I looked up that medication and it is a pain reliever designed for cats, although I've never heard of it before....

I have the same problem. Daisy is very sensitive to bladder infections and bladder stones. I give her special food but every now and then she will get a bladder infection again. Probably because of stress., lower resistance.
Last time, it was a bacterial infection. Not the most common cause for bladder infections in cats.

She had metacam/novacam for a few times, but I really don't want to give this medication to my cats anymore, since I read very bad things about it. Most vets over here describe it easily, they say it's safe, even for cats with kidney failure. (I guess they never read the instructions since it has a contraindication for cats with bad kidneys).

Anyway, I asked my vet for another medicine. This was not for the bladder problem though. Daisy was injured so she needed painkillers again.
The vet gave me onsior.
In my experiece, it was helpful and I read it's less harmful for cats. Many people say it's safer than metacam.
So if my cats need painkillers I'll ask for onsior or tolfedine. No metacam!
Daisy ate these pills like candy, so that's a plus too

I took Haze back yesterday(Sunday) instead of Monday because he seemed uncomfortable. Why wait a day? He sat 5 hours at the vet with no urination again! The vet tried to do a cystocentesis but Haze was not having it and the vet said his bladder is so small that there was too much room for error. They gave me a urine collection kit to try at home. I quickly cleaned one of my smaller litter boxes out and picked up Haze and the kit. My cats do not use bags in their litter box so Haze was not liking this collection kit. I could tell he had to go so bad so I removed the bag, poured the pellets directly into the litter box and he immediately urinated! Yes!

No.

I realized I didn't clean ALL the litter dust out of box and it now was mixed in with the urine. !!!!! The vet couldn't take it. After three days of trying to catch enough urine, I was worn out. I had been doing research on D-Mannose. A wonder supplement! I gave a 1/2 teaspoon every hour for 4 hours and the urinary frequency stopped! Like within the two hours! I think the d mannose combined with the anti inflammatory Onsior helped make the infection and/or cystitis pass. I did notice the mannose caused diarrhea so after the 4 hours as suggested, I did 1/4 tsp in the morning. It's unbelievable! I want to thank the posters on this site because I learned of d mannose here. Thank you thank you to all that have posted about d mannose on any and all threads on here

I would still try to get another urine sample. D mannose is for infections. Infections are rare without having urinary crystals as well. If he has crystals he will need a change in food to prevent the urinary problems from recurring.

My point is he may get better now but relapse in a few months from now.

My cat was diagnosed with idiopathic cystitis. He was passing crystals inconsistently and the vet missed it on urinalysis. It took an entire year for a proper diagnosis. If I hadn't used my microscope I don't think we ever would have gotten a diagnosis. By then he had scarring of the urethra and he will always strain.

It has taken over two years to get him to stop having accidents. He still strains but at least uses the box. He has accidents much less frequently.. he's not cured through.

If we had gotten him treated the first time I brought him in, I could have avoided needing to replace the carpeting. I could have avoided the $1000 worth of vet bills. I could have avoided watching him suffer...

I suggest getting a urinalysis done on a yearly basis, at a minimum. It is much cheaper to prevent urinary problems than fix them. Especially now that you know your cat may have some issues. For some reason some cats are much more likely to develop urinary issues than others. This could be a warning that your cat may be one of those that needs special care.

Get that urinalysis done and make sure your vet tells you what the urine ph is! If you find his urinary ph is too high or low you need to try different foods until you find one that keeps his ph in the healthy range. Infections can cause the ph too get higher than normal. You may need to repeat the urinalysis after antibiotics if he has an infection....

I can't stress how important this is. One blockage while you are at work can kill your cat and is extremely expensive to treat if you catch it in time.

Watch the litter box and count pees. And get your cat back in to the vet if he starts having accidents again

Good luck.

Vets who have an ultrasound machine can be very precise when obtaining urine because they image the bladder as they do it.  If your vet doesn't have one of these maybe there is another vet who does?

Took Haze back in today so they could try to get another specimen. He was up all night trying to urinate.They were able to get a small sample and it showed no crystals or infection. The vet thinks it's cystitis. I'm so confused because he is trying to urinate every 5 minutes-sometimes going and sometimes not. He has already taken his 3 days of Onsior. I asked if this could be behavioral just as a last resort but really this has just developed in the last 5 days. I've had him for 6 weeks with no trouble so far. And since he is 9 months old, the vet said the likelihood of him having a bacterial infection is small. He was more concerned about a blockage but after the small urine check and X-ray, that didn't seem to be the case. I explained after almost breaking down that my fear is that I lost my 5 month old kitten due to an undiagnosed congenital kidney disease with UTI just 3 months ago and I'm hyper vigilante about watching for signs. I don't want this being tossed aside As something that will just subside in time. He said to try the nurturecalm collar to see if stress is causing the cystitis and stay in touch over the next day or two and if need be we can sedate Haze and get a better sample that way.

By giving haze the D mannose could I have masked the infection during urinalysis?
