Hypokalaemia in Cats: Welfare Management

Key Welfare Considerations

• Potassium is critical for normal neuromuscular welfare function — low levels cause profound muscle weakness.
• Hypokalaemia causes ventroflexion (downward neck dropping) as a characteristic welfare posture in cats.
• Generalised muscle weakness from hypokalaemia welfare causes reluctance to walk, climb, or eat.
• Chronic kidney disease is the most common welfare cause — reduced renal tubular potassium reabsorption.
• Hyperthyroidism, hyperaldosteronism, and dietary insufficiency are additional welfare causes.
• Serum potassium below 3.5 mmol/L indicates hypokalaemia — below 2.5 mmol/L causes severe welfare signs.
• Oral potassium gluconate supplementation is the primary welfare treatment for mild to moderate hypokalaemia.
• IV potassium chloride supplementation is welfare-necessary for severe hypokalaemia or when oral intake is impossible.
• Rate of IV potassium administration must not exceed 0.5 mEq/kg/hour to prevent cardiac welfare complications.
• Underlying cause treatment is essential — simply supplementing potassium without addressing CKD is welfare insufficient.
• Potassium-replete renal diets support welfare potassium maintenance in CKD cats.
• Monitoring serum potassium at regular welfare intervals ensures adequate supplementation levels.
• Hypomagnesaemia can perpetuate hypokalaemia — magnesium welfare status assessment may be needed.
• Muscle soreness and discomfort during recovery from severe hypokalaemia requires welfare analgesic consideration.
• Long-term welfare prognosis depends on the underlying cause — CKD management is central to potassium welfare control.
