Our Story

Our Beginning

In 1999, the most wonderful, playful long-haired feline arrived on my doorstep. This little ball of fur meowed, purred, snuggled, and followed my every move for well over 17 years.

Named SEVEN after my favorite Denver Broncos' MVP, we had many great adventures together in spite of the fact that I was extremely allergic to cats and he was battling a series of skin allergies that required him to wear a t-shirt most of his adult life.

Seven was a game changer for me, opening my eyes to a healthier, cleaner way of life. As we both got older, nutrition became more and more important. Searching store after store for the right ingredients and brands. Reading labels to avoid potential allergens, fillers, chemicals, and artificial ingredients. Moderating our eating habits. Exercising. And choosing a more organic, all-natural diet - a focus that extended his life for a full year, even after diagnosed with kidney disease.

Pets by Nature was created to carry forth Seven’s legacy:

Healthy food = Happy pets.

Our Mission
