Cat Hypocalcemia: Low Calcium Emergencies in Cats

Hypocalcemia is a potentially life-threatening drop in blood calcium in cats, most often seen after thyroid or parathyroid surgery.

Key Facts

Post-surgical hypocalcemia can develop within 24 to 72 hours of thyroidectomy
Symptoms include muscle tremors, seizures, and facial rubbing
Parathyroid gland damage during surgery is a common cause
Treatment involves IV calcium gluconate in acute cases
Long-term oral calcium and vitamin D supplementation may be needed

Welfare Considerations

Acute hypocalcemia causes severe neuromuscular signs including tetany and seizures that are deeply distressing for affected cats. Prompt recognition and treatment are critical to prevent suffering and death. Post-surgical monitoring protocols significantly reduce risk.

What You Can Do

Monitor cats closely after thyroid surgery for signs of low calcium
Know the warning signs: muscle twitching, weakness, seizures
Ensure your vet provides post-op calcium monitoring guidance
Give prescribed supplements exactly as directed
Contact a vet immediately if neurological signs appear post-surgery
