Feline Chronic Kidney Disease: Welfare and Management

Chronic kidney disease is the most common serious illness in older cats and a major source of welfare burden affecting millions of cats worldwide.

Key Facts

CKD affects an estimated 30-40% of cats over 12 years of age
The condition causes nausea, reduced appetite, weight loss, and dehydration
Early detection through regular bloodwork allows slower progression
Dietary modification with reduced phosphorus slows disease progression
End-stage CKD causes uraemic encephalopathy with severe suffering before death

Welfare Considerations

Cats with advanced CKD experience chronic nausea, reduced quality of life, and end-stage uraemia that is deeply unpleasant. Regular veterinary monitoring of older cats allows early intervention that extends good quality life. Owner recognition of subtle signs including increased water intake and weight loss is critical. Timely euthanasia when quality of life cannot be maintained is an important welfare consideration.

What You Can Do

Take cats over 7 years for annual veterinary checks including blood and urine tests
Learn early signs of kidney disease including increased thirst and weight loss
Follow dietary recommendations for cats diagnosed with CKD
Work with your vet to monitor quality of life using validated assessment tools
Discuss end-of-life care and euthanasia timing openly with your vet for cats with advanced CKD
