Radioactive Iodine Treatment
Radioactive iodine is widely considered the gold standard treatment for cats of any age with hyperthyroidism due to its simplicity, effectiveness and safety. Without treatment, hyperthyroidism can lead to severe symptoms and even become fatal.
At Cat Specialist Services, we have a dedicated facility for treating hyperthyroidism in cats using radioactive iodine (I-131). This highly effective treatment involves administering a single capsule, which is usually well-tolerated by cats and has a high success rate. Most cats return to normal thyroid levels within a few weeks of treatment.
Ureteral Bypass Catheter
The Subcutaneous Ureteral Bypass (SUB) is a surgical procedure designed to bypass blockages in the ureter, allowing urine to flow from the kidneys to the bladder. This advanced, life-saving intervention is often necessary when obstructions, such as kidney stones, prevent normal urine drainage. The procedure involves placing a small tube, or bypass, that reroutes urine flow around the obstruction.
Ureteral obstructions can severely damage the kidneys and lead to kidney failure if left untreated. Complete obstructions can become fatal within 48-72 hours without intervention. Regular monitoring and care of the SUB device help ensure long-term kidney function and reduce complications.
Sinus Trephination
At Cat Specialist Services, we are trialing an innovative treatment for cats with chronic rhinosinusitis caused by Pseudomonas infection.
Pseudomonas bacteria can normally exist in a cat’s nasal passages, but in cats with previous cat flu infections or other underlying diseases, it can cause severe infections.
It often invades the bones of the nose and sinuses, leading to extensive damage over time while developing resistance to standard antibiotics.
Frontal sinus trephination involves creating a small hole in the bone to flush out accumulated material, such as pus, and improve sinus drainage.

Frequently Asked Questions
What specialist treatments do you provide for cats?
We offer advanced procedures to manage complex feline conditions. These may include radioactive iodine therapy, ureteral bypass surgery and other specialist interventions.
What is radioactive iodine treatment for cats?
Radioactive iodine therapy uses a small dose of iodine to target overactive thyroid tissue in cats with hyperthyroidism. The treatment is usually given as a single capsule.
What is a ureteral bypass procedure?
A ureteral bypass catheter is used to redirect urine flow when a blockage prevents normal drainage from the kidneys. This procedure helps protect kidney function in affected cats.
Are specialist treatments available for chronic nasal infections?
Yes. Some cats with chronic rhinosinusitis may be treated with procedures such as sinus trephination when infection is caused by bacteria such as Pseudomonas.
How do you determine which treatment a cat needs?
We assess each cat through consultation, diagnostic testing and clinical evaluation before recommending treatment.

We transported our cat here from another animal hospital, as his condition was too complex for them. Our pet was given the highest quality of care, multiple investigations/procedures being able to be done at the one place a godsend. We were kept up to date frequently throughout his stay. All questions & options explained thoroughly. Being able to have private visits certainly helped us and our cat too. I would highly recommend Cat Specialist Services at Underwood. Amazing staff from reception, vet nurses, vets & specialists. Oh, and yes he is recovering wonderfully at home.

So very happy we were asked to come here for advice for our NORBIT. He has had 2 x UTI blockages within weeks of each other since turning 6. Surgery seemed to be his only option and he didn’t feel it was very fair on him if we didn’t at least exhaust all other avenues first.
Dr Allison was very thorough in her tests and has let us know she would like to treat the cause of the problem. Great news.
It may lead to removal of crystals in his bladder if his diet doesn’t let him pass them naturally.
At least this surgery won’t be as severe at taking his penis off him – so as his fur parents – we are very happy with this.
We await further tests to see what’s in store for him.
NORBIT will now be a patient of the clinic as we are so far very happy with his treatment thus far.

Hi has only been a week since losing my beautiful Peaches but can’t thank Dr Cindy, Maree and Jackie enough for the tender care they gave her and they after care they gave me. I sincerely thank them and can’t recommend the Clinic highly enough they are such caring people. Peaches I’m happier times.

I cannot thank the entire CSS team enough and especially Dr Cindy for the care they provided for our boy with a urinary blockage, and we will be taking both our cats here from now on. The clinic is exceptionally clean and calming compared to all other clinics we’ve been too, and all staff from the reception to the nurses/vets were so supportive during a stressful time. I knew from the first minute that I got to see him after he was transferred that he was in the best place, and that the staff genuinely care about their well-being and positive long term outcomes. We were given regular updates and full transparency, so much information including QR video codes on how to administer medications, along with print outs and emails about how to best help avoid future issues or recurrence. Our boy got to smooch on everyone and was beyond well looked after. Thank you again, you all made an incredibly stressful situation actually manageable and calming.

Dr Wan-Ju has been treating my baby since her first seizure in November 2025 and she has been fantastic.

Thank you team!

Dr Alison Jukes from CSS Underwood is an AMAZING feline physician. She is kind, professional, thorough and our cat is blessed to have her on his side. She even was able to save us money and invasiveness by being skilled to the level of doing ultrasound on two separate occasions without our cat needing to go under full sedation. Our other cat was recently seen by Dr Jukes as well, and she made sure our cat’s heart was ok. I also want to thank the lovely Jacqueline and Mairead from customer care. They are very kind each time I see them and call up. Sending thanks from our family, including Smokey and Floozy!

My whole experience with CSS was positive – from the first email I received giving lots of information regarding the process of radioactive iodine treatment to the expected costs, to checking my cat in for the treatment, boarding for 2 weeks after the treatment and picking her up to come home. They didn’t push for any tests that were not necessary.

We never knew this service existed but we are very grateful we were referred to them. Our vet Cindy was really great, she made us feel at ease during a very stressful time. We got the sense straight away the Leo was in good hands. This service made us feel better knowing that they specialise is cats only. Would highly recommend their services

My Lani finished her I-131 treatment today and I am beyond impressed with the way she was looked after. I am by definition a neurotic pet owner and sending my fur child away for a week was seriously daunting.
I was given daily updates about how kitty was eating, toileting and behaving. This really put my mind at ease. Vets and vet nurses were so accomodating and allowed Lani to have her favourite foods from home prepared her favourite way.
Her vet was so thorough when explaining her treatment and condition to me.
The ladies at reception were so friendly and understanding.
I honestly cannot recommend this clinic enough and I am so thankful for the positive experience Lani and I have had.

My sweet ginger boy Louis was hospitalised at CSS for a Urinary Obstruction. Dr Cindy and all the reception staff were amazing and empathetic. I would often ring up with questions post procedure and Dr Cindy would make time to talk and explain things to me
