Cat Hypokalaemia Welfare

Hypokalaemia (low blood potassium) causes painful muscle weakness in cats, particularly those with chronic kidney disease, with supplementation providing rapid welfare improvement.

Key Facts

Hypokalaemia in cats causes generalised weakness including inability to raise the head
CKD cats lose potassium through the kidneys at higher rates than healthy cats
Affected cats show ventroflexion of the neck and profound generalised weakness
Oral potassium gluconate supplementation corrects hypokalaemia rapidly
Some cats require long-term supplementation to maintain adequate potassium levels

Welfare Considerations

Hypokalaemia causes severe muscle weakness and distress. Diagnosis and potassium supplementation provide rapid welfare improvement, often within days.

What You Can Do

Discuss potassium supplementation with your vet for CKD cats showing muscle weakness
Monitor for ventroflexion of the neck as a specific sign of hypokalaemia
Provide potassium-appropriate diet for cats with known hypokalaemia tendency
Test potassium levels at every CKD monitoring appointment
