Cat Kidney Disease
Treatment Cost UK
Managing cat kidney disease costs £50 to £150 per month in the UK in 2026. This includes prescription renal diet, medications, and regular blood and urine monitoring. Early-stage disease is cheaper to manage than advanced stages.
What You Will Pay
Chronic kidney disease (CKD) is the leading cause of death in cats over 10 years old, affecting approximately 30-40% of senior cats. While there is no cure, early detection and proper management can significantly extend life expectancy and quality of life. Understanding the costs involved helps you plan for the long-term care your cat will need.
| Component | Typical Cost | Notes |
|---|---|---|
| Diagnosis (bloods + urinalysis) | £100 – £200 | Initial work-up with SDMA test |
| Prescription renal diet (monthly) | £30 – £50 | Royal Canin Renal, Hill's k/d |
| Phosphate binder (monthly) | £15 – £30 | Ipakitine, Pronefra, Lenziaren |
| Blood pressure medication | £10 – £25/month | Amlodipine for hypertension |
| Subcutaneous fluids (home) | £20 – £40/month | Prescribed for moderate-advanced CKD |
| Blood monitoring (each visit) | £60 – £120 | Every 3-6 months depending on stage |
early-stage CKD: diet + monitoring

advanced CKD: intensive management
Factors That Affect
the Price
Stage of kidney disease
IRIS Stage 1-2 is cheapest to manage (diet + monitoring). Stage 3 adds medications, phosphate binders, and possibly fluids. Stage 4 requires intensive management including daily subcutaneous fluids, multiple medications, and frequent blood tests.
Prescription diet compliance
Renal diets (£30-£50/month) are the single most effective intervention, proven to double survival time. However, some cats refuse them, requiring expensive appetite stimulants (mirtazapine £20-£30/month) or alternative approaches.
Monitoring frequency
Early-stage CKD needs blood tests every 6 months (£120-£240/year). Advanced-stage CKD may need monthly tests (£720-£1,440/year). Your vet will recommend appropriate monitoring intervals.
Concurrent conditions
Many cats with CKD also have hypertension (adds £10-£25/month for amlodipine), anaemia (EPO injections £50-£100/month), or hyperthyroidism (adds £30-£60/month). Multiple conditions significantly increase costs.
How to Save Money
Buy prescription diet online
Royal Canin Renal and Hill's k/d are 20-30% cheaper from online pet medicine retailers and retailers. With a vet prescription (£21 cap), buying online saves £80-£150 per year on diet alone.
Buy medications with a prescription
Amlodipine, benazepril, and phosphate binders are all available from online retailers at significant savings. A prescription for all ongoing medications saves £100-£200+ per year.
Learn to give subcutaneous fluids at home
If your cat needs fluid therapy, your vet can teach you to give subcutaneous fluids at home. A bag of Hartmann's solution costs £5-£10 versus £30-£50 per vet-administered session.
Get pet insurance early
If your cat is diagnosed with CKD, future insurance applications will exclude it as pre-existing. Insure cats from a young age — CKD costs can easily reach £1,500-£3,000+ per year in advanced stages.
Would insurance have covered this?
On a typical lifetime policy an owner pays the excess (usually £60–£200) and, on some policies, 10–20% of the rest. Pre-existing conditions are never covered, so the time to compare is before something goes wrong.

With proper management, cats diagnosed at Stage 2 can live 2-4 years or more. Stage 3 cats typically survive 1-3 years. Stage 4 is more variable, from weeks to over a year. Prescription diet and early intervention significantly extend survival.
Absolutely. Renal diets are clinically proven to double survival time in cats with CKD. At £30-£50/month, they are the most cost-effective treatment available and should be the foundation of management.
Yes, lifetime policies cover CKD diagnosis and management including diet, medication, blood tests, and fluid therapy — provided the condition was not pre-existing. CKD claims are among the highest value cat insurance claims.
Increased thirst and urination, weight loss, poor appetite, vomiting, bad breath, lethargy, and poor coat quality. Many cats show no signs in early stages — annual blood screening for cats over 7 catches CKD early when treatment is most effective.
