Advice needed - cat with kidney stones

Hi everyone,

I’m writing this because I’m at my wits’ end… I’ve been crying so much and I can’t stop thinking about it, it’s just so hard to deal with. I really need some advice and maybe some stories from anyone who’s been through something similar with their cat…

My cat Boboune, who’s about 6 years old, started vomiting quite frequently over the last few weeks and lost his appetite. I’d noticed about a year ago that he’d sometimes eat less, but it was usually temporary and he seemed better when I changed his dry food. But this time it was different.

One evening, he was sick a lot. Over the following days, he was sick less often but was eating less and less. As I had to go abroad, I left him with my parents, thinking I’d take him to the vet when I got back… but in the end, it couldn't wait.

The day after I left, Boboune stopped eating altogether. He was even throwing up water. I asked my parents to take him to the emergency vet, and that’s when they found his levels were through the roof:

  • Creatinine: 13.37

  • Urea: 248.65

The vet decided to admit him for 48 hours on an IV drip. The levels then dropped to:

  • Creatinine: 8.76

  • Urea: 217

It was a slight improvement, but still extremely high… My parents picked him up after that because it was a Sunday followed by a Bank Holiday Monday.

When I got back from my trip, I found him very tired, though he was still moving around a bit. He was eating a little, he wasn’t being sick anymore, but he was drinking loads.

The vet asked for an ultrasound. On Tuesday, the scan showed one kidney was very dilated and the other was an abnormal size, but she couldn't see any stones. A new blood test showed that the levels were climbing again… I was devastated.

I finally decided to take him to a 24-hour emergency vet clinic on Wednesday, hoping that intensive fluid therapy might still help…

The vet did another ultrasound and finally spotted several stones on both sides. He explained that some were near the bladder, which is quite encouraging, but others were near the kidney, which is more complicated.

He advised keeping him in for a few days on an IV drip to try and avoid complications or surgery. Another blood test is scheduled for tomorrow.

Today, he told me that Boboune was a bit lethargic, but that he’d wolfed down his meal, was passing urine, and clinically seemed to be doing quite well.

I’m so scared of losing him…

Has anyone else been through this with their cat? Is there still hope with levels this high?

The vet is mentioning possible stents, surgery for the stones, etc. But I don’t want to put him through too much if the long-term chances of success are low… not to mention the massive cost of the surgery.

Thanks in advance to anyone who takes the time to reply ❤

    Hi there,

    Based on the details you’ve described, it is clearly a case of severe kidney failure, likely obstructive or complicated by stones. However, the fact that he is urinating, eating, and responding to the drip is a positive sign in the short term. The levels are very high, but in veterinary medicine, we don’t make decisions based on the numbers alone: how he progresses on the drip, the presence of a partial obstruction, and his clinical response are vital for the prognosis. Options such as a stent or surgery are suggested specifically when there is still a possibility of restoring urinary drainage. It’s a serious situation, but not necessarily hopeless at this stage. The most important thing is to talk to the vet practice about the chances of actual functional recovery and the expected quality of life after treatment so you can make an informed decision.

    Kind regards,

    Romane

    Hello,

    I completely understand your distress… reading your post is truly heartbreaking 💔

    First of all, the fact that Boboune is eating again, passing urine and is still responsive is actually quite encouraging despite everything. With kidney levels that high, some cats unfortunately don't recover at all, so the fact he responded to the drip is significant.

    Stones can cause a blockage or severely damage the kidneys, but sometimes an extended stay in hospital and IV fluids can stabilise the situation enough for him to regain a decent quality of life, especially if some of the stones are more “accessible”.

    You also did the right thing by getting a second opinion at an emergency vet. In complex cases like this, it can really make a difference.

    I know we feel so much guilt at times like this (“I should have spotted it sooner”, “I should have acted faster”...), but honestly, you acted as soon as the situation became alarming. Cats often hide their symptoms for a very long time.

    Try to hold onto the small improvements day by day: that he’s eating, no longer vomiting, passing urine, being a bit more alert... these are details that matter a huge amount with acute kidney failure.

    My heart goes out to you and Boboune ❤️
