How dietary iodine restriction offers a non-invasive management option for feline hyperthyroidism and its welfare implications.
Feline hyperthyroidism is a significant source of suffering in older cats that is entirely manageable with appropriate veterinary care. Undiagnosed or untreated cats experience progressive weight loss, extreme anxiety and restlessness from elevated thyroid hormones, hypertension that can cause blindness or stroke, and cardiac disease. Early diagnosis through annual geriatric health screening and prompt treatment significantly improves quality and length of life. The availability of multiple treatment options including dietary management allows owners and veterinarians to tailor treatment to individual cat circumstances and owner capacity.
