Mirror is a 12-year-old DSH silver tabby. She is a happy, playful girl who loves her food. However, she began to experience slow weight loss and started jumping on counters to scavenge our food.
Initial Diagnosis and Examination
Mirror came to the clinic where Dr. Sarah performed an examination. Her physical exam was normal, except for her weight loss. Bloodwork and urinalysis were conducted, revealing an increased thyroid level, though her urinalysis was normal.
Understanding Hyperthyroidism
Hyperthyroidism is a disease that affects nearly all body systems. It is a potentially fatal condition but also a highly treatable one. There are three treatment options:
- I-131 (Radioactive Iodine): A curative treatment.
- Methimazole or Carbimazole: Daily or twice-daily medications that lower thyroid hormone levels.
- Y/D: An iodine-restricted food that can control thyroid levels if fed exclusively.
Although I-131 may seem expensive initially, when factoring the cost over five years, it actually becomes the more affordable option.
Deciding on Radioactive Iodine Treatment
When Mirror first started on her medication, she stopped eating for a day, which was unusual for her since she loves food. We decided she was a good candidate for radioactive iodine treatment. Scheduling her for the next treatment group, we concluded this would be the best option for Mirror’s lifestyle—and ours—since she was becoming difficult to pill.
The Radioactive Iodine Treatment
We made the drive to London to the Thames Valley Veterinary Services for her treatment. The friendly staff explained that Mirror would receive an oral dose of radioactive iodine. Many clients worry about their cat being stressed during the week-long stay post-treatment, but this was not our experience.
Mirror stayed at the hospital for a week while the radioactive iodine processed through her system, reaching a safe level to be around other animals and humans. We received daily updates on her progress. She was a superstar, enjoying the attention from the staff.
Mirror's Recovery and Current Health
Just over a year later, Mirror’s thyroid levels are within the normal range. She has gained weight and maintained it well. She is back to eating normally and is her playful, sweet self once again.
Today, Mirror is 14 years old, requires no medication, and we will continue with her yearly blood checks to ensure her ongoing health.
