I started my 10-year-old cat, Ninja, on Nature's Variety Instinct canned food a few weeks ago. In this short amount of time, my parents and I have noticed several fantastic changes in Ninja. Firstly, she absolutely loves this food. She ate a very small amount of food every day for years and we all just thought she had a small appetite. Turns out she just wanted some good food--and Nature's Variety is it. Secondly, she has gained weight already which she definitely needed. She is much more active, playing more often and being more social. Her coat is softer and she does not throw up like she used to! This food seems to have transformed my cat and I could not be more thankful. Wish I had given this to her years ago.
