Your checklist
R y/d is a complete and balanced diet for adult cats that need restricted iodine intake, with a great taste that cats love
R If you are concerned with any change in your pet’s condition, contact your veterinarian
R y/d is not recommended for growing kittens, pregnant or nursing cats
R If it is necessary to feed healthy cats in the household y/d, it is recommended that they each receive a tablespoon of an adult cat food daily to provide additional iodine
R For y/d to be effective it is critical that you follow your veterinarian’s instructions carefully and feed only y/d
R Only give medications or supplements that are recommended by your veterinarian
R Ensure you follow your veterinarian’s instructions with regard to check ups and repeat blood tests
R y/d must be stored in its original packaging
Because iodine intake from other food sources (treats, another pet’s food, etc.) can compromise
the effectiveness of low-iodine nutrition, it’s critical that you follow your veterinarian’s feeding
instructions carefully and feed only y/d.
IMPORTANT
These are general guidelines only. Cats with concurrent conditions such as kidney disease or diabetes need special
consideration. Your veterinarian will recommend a transition plan specific to your cat’s needs.

Signs of feline hyperthyroidism
Signs of hyperthyroidism can vary in severity
depending on how long a cat has been ill.
Signs of hyperthyroidism include:
Managing hyperthyroidism
Four potential options for managing
cats with hyperthyroidism:
Radioactive iodine therapy: radiation to treat abnormal thyroid tissue
Daily nutrition: limiting dietary iodine intake reduces excess thyroid hormone production
Daily medication: anti-thyroid drugs inhibit the production of thyroid hormones
Surgery: removal of abnormal thyroid tissue
What is hyperthyroidism?
The thyroid gland, located in your cat’s neck,
uses dietary iodine to make thyroid hormones
that help regulate important body functions
including your cat’s:
The importance of nutrition
Hill’s Prescription Diet™ y/d™ Thyroid Care
is the first and only clinically proven nutrition
to manage feline hyperthyroidism under
veterinary care.
If your cat has been diagnosed with
hyperthyroidism, feeding y/d carefully limits
the levels of dietary iodine to reduce excess
thyroid hormone production. If your cat has
been diagnosed with hyperthyroidism your vet
may recommend y/d.
n Weight loss
n Increased appetite
n Diarrhoea and/or vomiting
n Increased thirst
n Poor skin and coat condition
n Hyperactivity
Cats with chronic kidney disease and diabetes mellitus exhibit some signs similar to hyperthyroidism.
Your veterinarian may also need to perform tests for these diseases to ensure an accurate diagnosis.
If your cat has hyperthyroidism, his or her thyroid gland will be enlarged and be producing excessive
amounts of thyroid hormone.
Hyperthyroidism is a common feline
endocrine disorder, most often diagnosed
in older cats over the age of 10. Left
untreated, hyperthyroidism can have serious
consequences on vital organs such as
the heart and kidneys. The good news is,
this disease is highly manageable and can be
controlled with proper veterinary care.
