Cat Hyperthyroid Surgery and Welfare

Surgical thyroidectomy provides permanent cure for feline hyperthyroidism with specific welfare considerations around anaesthesia and post-operative monitoring.

Key Facts

Unilateral thyroidectomy cures hyperthyroidism in cats with single-gland disease
Bilateral thyroidectomy risks hypoparathyroidism causing dangerous hypocalcaemia
Pre-operative stabilization with methimazole reduces anaesthetic risk
Surgery avoids the isolation period required for radioiodine treatment
Some facilities offer simultaneous dental work under the same anaesthetic

Welfare Considerations

Surgical thyroidectomy in appropriately selected and prepared cats provides permanent cure without medication burden or radioiodine isolation. The anaesthetic risk is manageable with proper pre-operative stabilization. For some cats, surgery offers the best welfare outcome.

What You Can Do

Discuss surgical thyroidectomy with a specialist veterinary surgeon for your hyperthyroid cat
Ensure methimazole pre-treatment before surgery to reduce anaesthetic risk
Monitor calcium levels carefully in the first week post-operatively
