Feline Kidney Disease: Spotting Early Warning Signs & Providing Lifelong Care
Chronic Kidney Disease (CKD) is one of the most common conditions affecting aging cats, yet it often goes undetected until the disease has progressed. With early recognition and consistent care, many cats with CKD can live comfortable, fulfilling lives. At Harbor Pines Veterinary Center, we’re here to help you recognize early warning signs, understand your options, and provide the lifelong support your cat needs.
Understanding Feline Chronic Kidney Disease
What Is CKD?
Chronic Kidney Disease is a gradual decline in kidney function, most often seen in senior cats. The kidneys are responsible for filtering toxins from the blood and maintaining hydration and electrolyte balance. When function declines, waste builds up in the body, causing a wide range of health issues.
Common Causes of CKD in Cats
- Age-related degeneration
- Genetics – Some breeds like Persians and Siamese are more prone
- Infections and toxins – Including exposure to certain medications or lilies
- Underlying diseases – Such as high blood pressure or hyperthyroidism
- Polycystic Kidney Disease (PKD) – A hereditary disorder causing cysts in the kidneys

Recognizing the Signs: Early & Advanced Symptoms
CKD progresses slowly, which is why early symptoms are often missed. Being aware of the warning signs can lead to earlier diagnosis and better outcomes.
Early Signs to Watch For:
- Increased thirst and urination
- Mild weight loss
- Decreased appetite
Advanced Symptoms:
- Vomiting and nausea
- Lethargy or weakness
- Bad breath (uremic odor)
- Poor coat condition
- Behavioral changes like hiding or irritability
If your cat shows any of these signs, schedule an exam promptly.

How CKD Is Diagnosed
At Harbor Pines Veterinary Center, our diagnostic approach includes:
Physical Exam & Medical History
We look for clinical signs such as weight loss, dehydration, and changes in behavior.
Lab Testing
- Bloodwork: Measures kidney values like creatinine and BUN
- Urinalysis: Assesses urine concentration and protein loss
- Imaging: X-rays or ultrasound help evaluate kidney size and structure
Additional Testing
- Blood pressure checks – Hypertension is common in CKD and can worsen the condition
- Anemia screening – CKD can cause reduced red blood cell production

Treatment and Long-Term Management
While there’s no cure for CKD, many treatment options can slow disease progression and improve your cat’s quality of life.
Diet & Hydration
- Prescription Kidney Diets: Low in protein, phosphorus, and sodium to reduce kidney workload
- Wet Food & Hydration Support: Encourage water intake with fountains or wet food
- Subcutaneous Fluids: May be recommended at home to maintain hydration
How to give subcutaneous fluids
Medications
- Phosphate Binders: Prevent dangerous phosphorus buildup
- Blood Pressure Medications: Help preserve kidney function
- Erythropoiesis-Stimulating Agents: Support red blood cell production to manage anemia
Ongoing Monitoring
Regular exams are key. We recommend:
- Bloodwork every 3–6 months or more
- Urine checks
- Blood pressure monitoring
- Weight, vomiting, and appetite tracking
At-Home Support: Comfort & Quality of Life
Managing Daily Life with CKD
- Provide quiet, stress-free environments
- Use orthopedic or heated beds for older cats
- Keep litter boxes easily accessible
- Monitor appetite and energy levels daily
Planning Ahead: Palliative and End-of-Life Care for CKD
While many cats with CKD can live well for months or even years, it’s important to understand that chronic kidney disease is progressive and ultimately terminal. Over time, kidney function will continue to decline—even with the best management.
Why Planning Matters
Creating a care plan early helps ensure your cat remains comfortable, your family feels prepared, and no decisions are made during moments of crisis. This may include:
- Establishing quality-of-life goals
- Identifying signs that may indicate suffering (such as persistent vomiting, refusal to eat, or extreme lethargy)
- Discussing hospice or in-home euthanasia options
What Palliative Care Looks Like
Palliative care focuses on comfort, not cure. This may involve:
- Pain management
- Appetite stimulants or anti-nausea medications
- Increased fluid therapy
- Adjusted feeding routines
- Emotional support for both the pet and family
Our veterinary team will help guide you through these discussions with empathy and honesty—ensuring your decisions are informed, compassionate, and aligned with your pet’s needs.
When to Seek Immediate Veterinary Care
Prompt intervention is crucial if your cat experiences:
- Severe lethargy
- Vomiting or diarrhea
- Refusal to eat or drink
- Sudden weight loss
- Dehydration
