About Us

Our Why

Where Pets Thrive

MailboxPet was founded on a simple belief: every pet deserves the same proactive health care we give ourselves. We started because we couldn't find a single destination that combined personalized pet health assessments with premium, vet-informed supplements delivered straight to your door. So we built it.

Today, thousands of pet parents trust us to help their dogs and cats live longer, healthier, more vibrant lives — one monthly box at a time.

Our Mission

We believe preventive pet health care shouldn't be complicated or expensive. Our mission is to make it effortless for every pet parent to give their companion the foundational nutrition they need — multivitamins, probiotics, joint support, digestive health, and more — customized to their pet's exact profile and delivered monthly.
