Pet Insurance that covers kidney disease in Australia

Summary

Kidney disease: a worrying diagnosis

The diagnosis of kidney disease in a beloved dog or cat is worrying and stressful for pet parents. When you realise how common kidney disease is, and how expensive treatment can be, it’s easy to understand why pet owners are concerned.

This article explains how kidney disease affects Australian pets, what treatment can cost, and what to look for when researching pet insurance that covers kidney disease, including how Bow Wow Meow’s Nose-to-Tail Cover fits in.

Understanding kidney disease in pets

Chronic kidney disease (CKD) is a long-term condition where the kidneys gradually lose their ability to filter waste products and maintain fluid and electrolyte balance. Over time, more and more nephrons (the tiny functional units of the kidney) are damaged and lost. Once nephrons are gone, they generally do not grow back, so CKD is considered progressive and usually irreversible, requiring ongoing management rather than a one-off “cure”.

International expert groups such as the International Renal Interest Society (IRIS) describe CKD in dogs and cats as a progressive, often irreversible disease that typically needs long-term monitoring, dietary changes, blood pressure control and supportive treatment to slow progression and maintain quality of life.

Even though CKD may start silently, it becomes a major issue because:

• It tends to worsen over months to years

• It can lead to complications such as anaemia, high blood pressure and dehydration

• It often requires lifelong management, including prescription renal diets, frequent blood and urine tests, blood pressure checks and sometimes fluid therapy

Prevalence of CKD in dogs and cats

Several major bodies, including IRIS and ISFM, highlight that CKD is one of the most frequently diagnosed diseases in older cats and an important cause of illness in dogs.

From a population perspective, CKD is not rare:

• Overall, CKD affects an estimated 0.5 to 1% of dogs and 1 to 3% of cats in the general population, with prevalence increasing in older age groups.

• Its incidence increases dramatically with age, especially in cats. Multiple studies put prevalence at 30–40% of cats over 10 and up to 80% of cats over 15, making CKD one of the most common problems seen in senior cats in both Australian and overseas practices.

Australian and UK sources commonly describe CKD as one of the leading health issues in older cats, often discovered during investigations for weight loss, increased thirst or poor appetite.

Age-related risk

Age is one of the strongest risk factors:

• The prevalence of CKD rises sharply in cats from about 9–10 years of age, with geriatric cats overwhelmingly represented in CKD cohorts.

• In dogs, CKD is less common than in cats but still more frequently diagnosed in middle-aged and senior dogs, with some studies suggesting that around 10% of dogs may develop some form of kidney disease over their lifetime.

Because early CKD can be quite subtle, routine blood and urine tests in senior pets are a key way to detect kidney changes before obvious symptoms appear.

Mortality and impact on quality of life

CKD generally has real impacts on longevity and wellbeing:

• ISFM guidelines note that renal disease was the most common cause of mortality in cats >5 years of age in a UK study, responsible for over 13% of deaths.

• CKD is described as a leading cause of morbidity and a major welfare concern in geriatric cats, because it affects appetite, weight, hydration, blood pressure and overall comfort.

With good supportive care, many dogs and cats with CKD can enjoy months to several years of good quality life, but that support comes at the cost of frequent vet visits, tests and medication. Expenses can  quickly mount up to thousands of dollars in vet bills, which is where pet insurance can help.

How much does kidney disease treatment & management cost?

The cost of managing kidney disease in pets varies widely because CKD is not a single event; rather, it is an ongoing condition that can require:

• Repeated blood and urine tests

• Blood pressure monitoring

• Prescription renal diets

• Medications (e.g. blood pressure drugs, phosphate binders, anti-nausea medication)

• Fluid therapy (sometimes including at-home subcutaneous fluids)

• Occasional hospitalisation, especially during crises such as dehydration or acute kidney injury on top of CKD

PetSure’s Pet Health Monitor gives us an idea how expensive chronic kidney disease can be, ranking it the 5th most expensive health condition in Australian dogs during 2024.

^ØBased on PetSure claims data, 2024 calendar year. Reimbursement for these claims under a pet insurance policy would be subject to limits, such as annual benefit limits or sub-limits, benefit percentage, applicable waiting periods and any applicable excess. Cover is subject to the policy terms and conditions. You should consider the relevant Product Disclosure Statement or policy wording available from the relevant provider. Please note that values calculated are based on all claims for that condition and medically related conditions in each calendar year.

CKD is a classic “chronic condition” for which pet insurance that includes illness cover, a high annual limit and no restrictive sub-limits, such as our Nose-to-Tail Cover, can be particularly valuable. As long as it is not a pre-existing condition, and onset occurs after the 30-day waiting period, it should be eligible for cover.

Because it is difficult to predict the costs of veterinary care, it can help to have measures in place to help prepare for the unexpected. Pet insurance can help by covering a portion of the eligible vet bill if the unexpected does happen.

Why is the cost of kidney treatment so high?

Diagnosis

Diagnosing CKD and distinguishing it from acute kidney injury often requires:

• Comprehensive blood tests (urea, creatinine, SDMA, electrolytes)

• Urinalysis, including urine specific gravity and protein:creatinine ratio

• Blood pressure measurement

• Imaging such as ultrasound to assess kidney size and structure

• Sometimes further tests to look for underlying causes (e.g. infections, stones, endocrine disease)

These tests are often repeated over time to confirm that changes are chronic and progressive, and to stage the disease according to IRIS guidelines for treatment planning.

Treatment and hospital care

CKD is usually not cured, but managed. Costs can include:

• Hospitalisation and IV fluids during crises (e.g. dehydration, uremic episodes)

• Medications to control high blood pressure, nausea, gastric ulcers and anaemia

• Treatment of associated urinary tract infections or stones

• Procedures for complications, such as placement of feeding tubes in cats that stop eating

Each admission or procedure carries its own fee, and because CKD tends to wax and wane, there may be multiple acute episodes over the pet’s remaining lifetime.

Maintenance and lifelong monitoring

Most of the cost of CKD comes from ongoing management rather than one-off emergencies:

• Regular blood and urine tests (for example, every 3–6 months, sometimes more often)

• Blood pressure checks and medication adjustments

• Prescription renal diets – which can meaningfully slow disease progression and improve survival, but are more expensive than standard diets

• Subcutaneous fluids and syringes if given at home

• Periodic follow-up consultations to monitor weight, hydration and clinical signs

Studies show that cats fed veterinary renal diets can live two to three times longer than cats with CKD on regular diets, but this extended survival also means more time spent on monitoring and treatment.

Does pet insurance cover kidney disease?

Many owners only start thinking about insurance when their vet first mentions “kidney disease” on blood tests and they realise treatment won’t be a one-off visit.

CKD as an illness under pet insurance

In Australia, chronic kidney disease is generally treated as an illness under pet insurance policies. That means it is typically covered under Comprehensive policies that include illness cover.

For CKD to be covered:

• Clinical signs or abnormal test results usually need to arise after the policy starts, and

• Be outside any illness waiting periods, and

• Not be considered a pre-existing condition (e.g. kidney changes or high kidney values documented before cover, or during the waiting period)

If these conditions are met, CKD can often be claimed as an ongoing chronic condition over multiple policy periods, subject to normal limits.

Chronic conditions and long-term claims

Unlike a one-off accident, CKD can generate repeated claims over months or years for lab monitoring, check-ups, medications and dietary management. Many insurers treat CKD like other chronic conditions (e.g. diabetes, arthritis):

• As long as the policy is kept continuous and subject to the PDS, the condition may remain eligible for benefits in future years

• Each year, benefits are usually capped by that policy’s annual benefit limit and any relevant sub-limits

How Bow Wow Meow Pet Insurance approaches chronic conditions

Bow Wow Meow’s Nose-to-Tail Cover is an Accident & Illness policy that:

• Offers annual benefit limits of $10,000, $20,000 or $30,000, depending on the level chosen^⑅

• Reimburses up to 90% of eligible vet fees (subject to the chosen benefit percentage and any excess)^⑅

• Has no sub-limits – meaning there are no smaller caps specifically for kidney disease, blood tests or other particular conditions; the entire annual limit can be used where it’s most needed

Kidney disease is not treated as a special separate category: like other illnesses, CKD is generally covered as long as it is not pre-existing and the policy’s terms are met, including waiting periods and exclusions.

This means that potentially you can claim up to $30,000 per year for CKD related vet bills, if you have taken out Nose-to-Tail Cover with a $30,000 annual limit^⑅.

Bear in mind that Nose-to-Tail Cover is subject to waiting periods, pre-existing condition rules and other terms and exclusions set out in the current PDS.

Researching pet insurance providers

Here are some steps you can follow to research pet insurance providers:

• Check the ratings of the pet insurance companies you are considering on independent rating sites like productreview.com.au and Google ratings. Existing and previous customers and can provide a lot of valuable information, especially when it comes to customer service.
• Make a shortlist of pet insurance providers that suit your needs and budget. You should look for three or four that offer the coverage you need, the price you can afford, and the customer service you expect.
• Do some online research of the pet insurance providers you are interested in. Have a look at their websites to get a feel of the company. Are they focused exclusively on pets, or is pet insurance just one of a range of types of insurance they provide?

• Compare the quotes and coverage of different pet insurance providers. You can usually do this online, but in many cases you can also contact the insurance companies directly and ask for quotes and details about their cover and benefits if this is an easier option for you.
• When reading PDS documents online, you can search for key phrases such as “kidney disease”, and “renal disease” to understand how the insurer specifically handles CKD coverage. Specifically, you want to see these terms listed as covered illnesses.

Choosing a pet insurance policy that covers kidney disease

Once you’ve narrowed down a few options, it’s time to look closely at the structure of the cover. Be sure to thoroughly research the following important considerations:

Annual limits and sub-limits

Because CKD can involve many small, repeated costs and occasionally large spikes (e.g. hospital stays), look for a policy with:

• A high annual benefit limit (e.g. $20,000 or $30,000 rather than a very low cap)

• No sub-limits on diagnostics, prescription diets or kidney-related conditions

Bow Wow Meow’s Nose-to-Tail Cover has no sub-limits and up to $30,000 annual limit, giving you flexibility to use the full annual limit on CKD management and treatment, if required, in a given year^⑅.

Ongoing cover

Most modern policies are designed to cover ongoing conditions year after year, provided you keep your policy continuous (i.e. you continue paying your premiums).

Excess and waiting periods

Check:

• How often the excess applies – some excess are applied per condition and others only once per policy period (including our Nose-to-Tail Cover)
• The illness waiting period and whether any longer waiting periods apply to specific conditions

These details can affect how your pet insurance kidney disease claim plays out if your pet is diagnosed soon after you take out the policy.

Pre-existing conditions

Like other illnesses, CKD is unlikely to be covered if there were signs or abnormal kidney values before the policy started, or during the waiting period. That includes subtle signs like:

• Elevated creatinine or SDMA on bloodwork

• Dilute urine and protein loss

• Weight loss and increased thirst in older cats

A sensible strategy is to take out pet insurance while your pet is young and still healthy, well before any kidney issues are detected.

Prevention and early detection

You can’t prevent every case of CKD, but you can reduce risk where possible and, importantly, pick it up early, when treatment is most effective and sometimes less costly.

Prevention and risk reduction

Helpful steps include:

• Hydration: Ensure constant access to fresh water; many vets recommend wet food or fountains for cats prone to dehydration.

• Healthy diet: Feed a balanced, life-stage-appropriate diet; avoid excessive treats and salty foods.

• Avoiding toxins: Keep lilies, certain human medications, anti-freeze and other nephrotoxic substances out of reach.

• Regular check-ups: Annual (or twice-yearly for seniors) vet visits help detect early changes in kidney values, weight and blood pressure.

Recognising early signs of CKD

Early signs can be easy to miss, especially in cats. Symptoms that warrant a vet visit include:

• Increased thirst and more frequent urination

• Weight loss and reduced appetite

• Vomiting or nausea

• Lethargy, reduced activity or hiding

• A dull or unkempt coat

• Bad breath with a “uremic” or chemical odour

Not all of these automatically mean kidney disease, but all are reasons to see your vet promptly.

In conclusion

Chronic kidney disease is common, especially in older cats, and is a major cause of illness and death in senior felines worldwide. Dogs are also often affected, particularly in middle and old age. CKD is progressive, usually irreversible and requires lifelong management, from renal diets and medications to frequent blood and urine tests.

The cost of diagnosing and managing kidney disease can run to many thousands of dollars, with some cases exceeding $50,000 according to Australian claims data. Bow Wow Meow’s Nose-to-Tail Cover offers high annual limits, up to 90% back on eligible vet bills and no sub-limits^⑅, features that can be very valuable for kidney disease in dogs and cats.
