Hopper was a handsome ginger 10 year old neutered male, but he had lost 0.5kg - about one eighth of his bodyweight - in the course of just one month. He had also developed a ravenous appetite, was very restless and had lost coat condition.

Hopper was referred to the Feline Centre at Bristol Veterinary School where, after tests, hyperthyroidism was diagnosed. A number of treatments are available for this problem, depending upon any other existing medical conditions. Medical treatment is an option but involves dosing a cat two to three times daily for the rest of its life and surgery can lead to post-operative complications. Radioactive iodine treatment is available at only a few centres around the country including, luckily for Hopper, the Feline Centre at Bristol.

It was agreed by the staff at the centre, after consultation with Hopper's owners, that he would be given the irradiation treatment but he had to spend five weeks in isolation. At Bristol, the isolation unit is spacious and comfortable and includes all that a recuperating cat could need, including comfortable bedding, things to climb and scratch and, of course, food and a litter tray.

When Hopper was discharged, he had made a remarkable recovery. He had gained 0.75kg in weight - more than he had lost! His heart rate and blood pressure had decreased and he had changed from a nervous, jumpy cat into one who was relaxed and happy to lie about, being pampered. Both staff and owners were delighted with the outcome, as, no doubt, was Hopper.
