Senior Cat Hyperthyroid Management

Welfare-centred management of hyperthyroidism in senior cats including treatment options, monitoring, and quality of life assessment.

Key Facts

Hyperthyroidism affects approximately 10% of cats over 10 years
Signs include weight loss, increased appetite, hyperactivity, and vomiting
Treatment options include daily medication, radioactive iodine, surgery, and dietary iodine restriction
Radioactive iodine is curative in over 95% of cases
Concurrent chronic kidney disease is common and complicates treatment decisions

Welfare Considerations

Hyperthyroidism causes chronic suffering in senior cats through cardiovascular strain, gastrointestinal disturbance, and systemic hypertension. While highly treatable, the choice of treatment method involves welfare trade-offs particularly regarding concurrent kidney disease. Close monitoring and regular reassessment ensure treatment maintains quality of life.

What You Can Do

Have cats over 10 years screened annually for hyperthyroidism
Discuss treatment options with your vet including long-term welfare implications of each
Monitor blood pressure and kidney function regularly in hyperthyroid cats under treatment
