New lease on life!!

by Michael -

Puck is a short haired Oriental and is 19 years old. He was having health problems about five years ago and a diagnosis pointed towards a Thyroid problem so I tried Hills y/d. He looks and feels absolutely wonderful now and is healthier now (touch wood) than when he was ten years old.

Can’t believe!

by Mindy -

After only 4 weeks my cats thyroid levels dropped to normal limits. She gained a bit of weight and is acting more like her old self. I am amazed at how well it worked.
