Alternative Treatments
Steroids, stem cell transplants, kidney transplants, and holistic remedies, with what the evidence actually shows.
Most CKD management centres on the same core treatments: diet, hydration, phosphorus control, and addressing complications as they arise. But you’ll also come across a wider range of options, some backed by real research and some backed mostly by marketing. This post rounds up the less commonly used treatments, from steroids and stem cell therapy to kidney transplants and popular holistic remedies, with an honest read on what the evidence actually supports.
Steroids
Steroids are not a routine or essential part of CKD treatment, and corticosteroids in particular are generally best avoided in cats with impaired kidney function unless there’s a specific reason to use them.
Corticosteroids
Corticosteroids like prednisolone are occasionally prescribed for a specific concurrent condition, such as inflammatory bowel disease, rather than for the CKD itself. Cats convert prednisone to its active form, prednisolone, fairly inefficiently, so prednisolone is generally the better choice if a corticosteroid is needed.
The risks are real and worth knowing. Corticosteroids can worsen or trigger diabetes, increase blood pressure, mask infections, and increase the risk of stomach ulcers and gastrointestinal bleeding, which is particularly unwelcome in a cat already prone to uraemia-related GI issues. There’s also a documented, if uncommon, association between starting corticosteroids and a rapid-onset form of congestive heart failure in cats, usually within the first week of treatment. If corticosteroids are ever discontinued, this needs to happen gradually rather than all at once, since abrupt withdrawal can suppress the body’s own natural cortisone production.
Anabolic Steroids
Anabolic steroids are used more in the UK than the US, generally as a general appetite stimulant or to help with muscle wasting, sometimes given as a monthly injection at the vet. They’re considered to have a narrower safety margin in cats than in dogs, with some concern about liver effects, so this is a treatment to discuss carefully with your vet rather than pursue on your own, and it’s not considered an essential treatment for most CKD cats.
Stem Cell Transplants
Mesenchymal stem cell therapy has a long track record in treating joint problems in horses and dogs, and there’s genuine scientific interest in whether it could help CKD cats too, since these cells can theoretically travel to damaged tissue and support repair.
In practice, the research in cats has been disappointing more often than not. Several controlled trials looking at intravenous stem cell infusion in CKD cats found no significant improvement in kidney function markers, even when the treatment itself was reasonably well tolerated. One early pilot study using cells injected directly into the kidney showed a promising short-term improvement in one cat, but this method required repeated sedation, which isn’t practical for most cats or caregivers. A newer wave of smaller studies, including some using repeated monthly treatments, has reported more encouraging bloodwork improvements, though the overall body of evidence remains limited and inconsistent.
Anecdotally, experiences shared by CKD caregivers are mixed. Some report no noticeable change, some report their cats feeling unwell for a few days afterward, and a smaller number report meaningful, lasting improvement. The procedure itself typically requires anaesthesia for fat extraction, which is an added consideration for an already unwell cat, and costs are substantial, often in the range of a couple thousand dollars or more. At this stage, most veterinary reviewers describe stem cell therapy for feline CKD as experimental and unproven rather than a reliable option.
Kidney Transplants
Kidney transplants are a real, if rarely used, treatment option, available at a small number of specialist centres, mostly in the US. A healthy young donor cat has one kidney removed and transplanted into the CKD cat, and the caregiver of the recipient is typically expected to give the donor cat a permanent home afterward.
This is major surgery on an already sick cat, and outcomes vary considerably by centre. Reported one-year survival rates across different transplant centres have ranged from as low as 60% to as high as 70 to 76%, with median survival times in the range of one and a half to three years at more experienced centres, though some cats have lived far longer. Recipients need lifelong immunosuppressive medication (usually cyclosporine) to prevent rejection, which brings its own risks, including a meaningfully increased chance of developing cancer or diabetes afterward. Complications like renal fibrosis in the new kidney have also been documented in a notable minority of recipients.
Cost is a serious barrier for most people, typically running well into the tens of thousands of dollars for the initial procedure alone, before ongoing medication and monitoring costs.
Availability also varies significantly by country. Transplants are not available in the UK at all, since the Royal College of Veterinary Surgeons does not support using a healthy living donor cat purely for the benefit of another animal, a position also held by major UK animal welfare charities. This is worth knowing if you’re researching transplants and wondering why you can’t find a UK provider.
Holistic and Complementary Treatments
Holistic medicine covers a lot of ground, from acupuncture to homeopathy to herbal remedies, and opinions on it run the full spectrum from enthusiastic to sceptical. Rather than treat holistic treatments as one category, it’s more useful to look at individual options on their own merits, since some are genuinely useful and others are, frankly, not worth your money.
Worth Considering
Slippery elm bark is the standout recommendation in this category. It’s a demulcent that soothes the digestive tract, and it’s commonly and successfully used for nausea, vomiting, mild diarrhoea, and constipation in CKD cats, with many caregivers seeing improvement within a day or two. It also seems to help with coat condition and hairballs. It’s inexpensive, widely available, and about as low-risk as a treatment gets, with one caveat: it contains calcium, so it’s best avoided in cats who already have elevated calcium levels, and it can reduce absorption of other medications, so should be given a couple of hours apart from anything else.
Acupuncture has a reasonable track record for helping some CKD cats feel generally better, and pain management in particular is one of its more evidence-supported uses in both human and veterinary medicine. It requires finding a trained veterinary acupuncturist, and while not every cat responds, it’s unlikely to cause harm when performed properly.
Approach with Caution
A number of popular products and ingredients marketed for kidney support are best avoided or used only with real caution:
-
Garlic is in the same plant family as onion and can cause a specific type of anaemia in cats, so it’s not worth the risk despite its reputation in human health circles
-
Cranberry is too acidic for CKD cats, who already tend toward acidosis, and it isn’t a good substitute for proper urinary tract treatment
-
Noni juice has documented cases of causing dangerously high potassium levels in human patients and offers no way to control dosing accurately
-
Dandelion and nettles are diuretics, which is generally the opposite of what a CKD cat, who’s often already losing too much fluid, needs
-
Essential oils and hydrosols should never be used around cats in any form. Cats lack the metabolic pathways to process them safely, and this applies regardless of how “pure” or “high grade” the oil is marketed as being. Documented cases of toxicity, including from tea tree oil specifically, back this up
-
Curcumin (turmeric) isn’t well studied in cats and may increase the risk of calcium oxalate kidney stones, plus there have been documented cases of turmeric products contaminated with lead
The Marketed “Miracle” Products
You’ll come across a steady stream of proprietary supplements claiming dramatic results for CKD, often built around amino acid blends, kidney glandulars, or other proprietary ingredients. A few, like AIM-based supplements, are riding real early-stage scientific research (in AIM’s case, a genuine protein being studied for its role in kidney repair) but the commercially available versions bear little resemblance to what’s actually been studied, and there’s currently no evidence any commercial AIM product improves kidney function in cats.
The general pattern worth watching for: bold claims that a single product can halt or reverse kidney failure, marketing that blames you for causing your cat’s CKD through diet choices, discouragement from using proven treatments like phosphorus binders or antibiotics, and a suspicious absence of any negative reviews. If a product checks several of these boxes, it’s worth being sceptical regardless of how many testimonials it has. None of this means every non-mainstream treatment is worthless, but “natural” and “holistic” aren’t the same as “harmless” or “proven,” and a genuinely effective miracle treatment for CKD would not need aggressive marketing to be well known.
Putting It in Context
None of the treatments in this post are essential for most CKD cats, and none should replace the core treatments (diet, hydration, phosphorus control) covered elsewhere on this site. Some, like slippery elm bark and possibly acupuncture, are low-risk and reasonable to try. Others, like kidney transplants and stem cell therapy, are significant undertakings worth researching thoroughly and discussing at length with your vet before committing to. And some are best left alone entirely. If you’re ever unsure where a specific product or treatment falls, that’s a good question to bring directly to your vet.
Frequently Asked Questions
Are steroids ever necessary for a CKD cat? Not routinely. They’re mainly used when a cat has a separate condition, like inflammatory bowel disease, that specifically calls for them, or occasionally as an appetite stimulant in the UK. They come with real risks in CKD cats and shouldn’t be used without a clear reason.
Is stem cell therapy worth trying for my cat? The research so far hasn’t shown reliable improvement in kidney function, and it’s expensive and requires anaesthesia. Some caregivers feel it helped, others saw no change. It’s reasonable to discuss with your vet, but it should be seen as experimental rather than a proven treatment.
Can I get a kidney transplant for my cat in the UK? No. UK veterinary and welfare organisations do not support the practice because of the ethical concerns around using a healthy donor cat, so transplants are not offered there.
Is slippery elm bark safe to use alongside my cat’s other medications? Generally yes, but give it a couple of hours apart from other medications since it can reduce their absorption. Avoid it if your cat has elevated calcium levels.
How do I tell a legitimate supplement from a scam? Be wary of any product claiming to halt or cure kidney failure on its own, marketing that blames you for your cat’s illness, advice to stop proven treatments like binders or antibiotics, and suspiciously perfect reviews. Real evidence usually comes with real limitations acknowledged, not just testimonials.
