Radioiodine therapy for feline hyperthyroidism is curative but involves isolation hospitalization that has welfare implications requiring thoughtful management.
The isolation requirement of radioiodine treatment creates a temporary welfare challenge for cats accustomed to owner contact and familiar home environments. The hospitalization period without owner visits causes stress in some cats, particularly those highly bonded to their owners. However, this temporary welfare cost must be weighed against the permanent welfare benefits of curing hyperthyroidism without daily medication stress. Pre-treatment strategies to reduce hospitalization stress include familiar bedding from home, consistent feeding schedules, and enrichment that does not pose radiation spread risks. Facilities specializing in feline radioiodine treatment have developed protocols specifically designed to minimize stress during the isolation period.
