Radioiodine (I-131) treatment is the gold standard, curative treatment for feline hyperthyroidism. At ARC, we provide radioiodine therapy for cats in a purpose-designed, feline-only environment that prioritises both medical outcomes and emotional wellbeing.
Our experienced veterinary team delivers radioiodine treatment with meticulous attention to safety, monitoring, and individual patient needs. Cats recover in our luxury cat condos, designed to minimise stress during hospitalisation, with adjustable under-floor heating, diurnal lighting, personalised enrichment, and a calm sensory environment — a level of care that sets us apart from traditional radioiodine facilities.
By combining advanced nuclear medicine with a genuinely cat-centred approach, we aim not only to treat hyperthyroidism effectively, but to ensure every cat feels safe, settled, and supported throughout their stay.
Whether your cat is staying with us for the week, or boarding with us, our stress-free feline accommodation offers a peaceful, health-focused alternative to traditional hospitalisation.
Inspired by cats’ natural instinct to perch and observe, the Treetops Condo offers a grounded, secure environment with subtle visual interest. Natural tones and textures create a calming space ideal for cats who prefer quiet observation and a sense of control.
Designed to promote relaxation and emotional calm, the Under the Sea Condo features cool, soothing colours and a serene sensory experience. This theme is particularly suited to anxious or sensitive cats who benefit from a low-stimulation environment.
Bright yet gentle, the Field of Daisies Condo evokes openness and warmth through soft daylight tones and calming imagery. It provides a reassuring, familiar atmosphere that supports rest, recovery, and positive emotional wellbeing.
The Beach Hut Condo blends warmth and comfort with a relaxed coastal influence. Balanced colours and subtle contrasts create a welcoming, homelike space suited to a wide range of feline personalities. Designed by veterinary professionals, each cat condo is individually prepared to suit your cat’s needs — because exceptional care begins with the right environment.
Radioiodine treatment is a safe, highly effective, and curative treatment for feline hyperthyroidism. It works by selectively targeting and destroying abnormal thyroid tissue while sparing healthy tissue, allowing thyroid hormone levels to return to normal.
Unlike lifelong medication or surgery, radioiodine treatment addresses the underlying cause of hyperthyroidism. In most cases, a single treatment permanently resolves the condition without ongoing medication, daily dosing stress, or surgical risks.
At ARC, radioiodine doses are individually calculated for each cat, based on an algorithm including thyroid hormone levels and patient/client-specific factors.This tailored approach allows us to deliver an accurate, effective dose rather than treating empirically. Individualised dosing optimises treatment success while reducing the risk of over- or under-treatment — a level of precision that sets our service apart.
Most cats stay with us for 6-7 days, as per the Department of Health's mandatory period. During this time, cats are closely monitored by our experienced veterinary team and recover in our purpose-designed luxury cat condos.
Cats undergoing radioiodine treatment stay in our premium, feline-only condos. Each condo features adjustable under-floor heating, diurnal lighting, personalised enrichment, optional red-light therapy, and a calm sensory environment designed to minimise stress during hospitalisation.
Yes. Radioiodine treatment has an excellent safety record and is well tolerated by the vast majority of cats. Side effects are uncommon, and our team carefully monitors appetite, behaviour, hydration, and overall wellbeing throughout the stay.
By the time your cat is discharged, radiation levels are lower than when in hospital. You will receive clear, written instructions outlining simple precautions to follow at home for a short period, ensuring safety for you, your family, and other pets.
Most cats require only routine follow-up blood tests with their regular veterinarian to confirm thyroid hormone levels have normalised. We provide detailed discharge instructions and remain available to support both you and your referring vet.
Most cats diagnosed with hyperthyroidism are excellent candidates. Even cats with concurrent conditions such as kidney disease may benefit, following careful assessment. We review every case individually to ensure radioiodine is the right option for your cat.
ARC combines advanced nuclear medicine expertise with a genuinely cat-centred philosophy. From individualised dose calculation to purpose-built feline accommodation and attentive monitoring, our focus is on achieving excellent medical outcomes while prioritising your cat’s comfort, wellbeing, and emotional health.
