Hills Prescription Diet Y/D (Thyroid Care) Dry Cat Food - 8.5lb/3.85kg

Managing Hyperthyroidism Through Diet.

Hyperthyroidism is one of the most common hormonal disorders in older cats. The overactive thyroid produces too much thyroid hormone, leading to weight loss despite a ravenous appetite, restlessness, increased thirst, and other symptoms. The thyroid gland needs iodine to produce thyroid hormones — and Hill's® Diet y/d® Thyroid Care uses a uniquely controlled iodine level to limit what the thyroid has available to work with.

When fed as the sole source of nutrition (no other foods, treats, or supplements), y/d® can help restore thyroid hormone levels to a normal range without medication — a remarkable option for cats whose owners prefer to avoid or can't use medical treatments. Some cats show improvement in thyroid markers within 3 weeks.

How It Works

• Strictly controlled iodine — limits thyroid hormone production
• Must be fed as the SOLE source of nutrition — no other foods, treats, or supplements
• Also supports kidney health with controlled phosphorus and low sodium
• Helps maintain healthy bladder mineral balance

Important: y/d® only works when it is the ONLY thing the cat eats. Any other food, treat, or flavoured supplement will introduce iodine that undermines the diet. Discuss compliance strategies with your veterinarian.
