      Imagine generating half a million dollars from hamster balls. What if you identified a market gap that had remained unchanged for 50 years and transformed it into a rapidly growing product business while still in college? That’s precisely what Ethan Haber accomplished with Happy Habitats, a small pet products company he founded during his sophomore year at Wake Forest University.

      While playing with his hamster Mooksie on campus, Ethan noticed someone walking a dog. This led him to ponder: why can’t I walk my hamster? That simple idea sparked a product line that is now expanding into 1,500 stores across the country through a significant retail deal.

      Ethan’s journey includes everything from cold-emailing a design firm and dealing with COVID shipping setbacks to successfully navigating Amazon and securing mentorship from PetSmart’s founder—all stemming from a niche most overlook.

      Transforming the Hamster Ball for Safety and Functionality

      The hamster ball's original design has barely evolved since its debut in the 1970s. Ethan recognized this as an opportunity, not a hindrance. The standard design featured genuine issues:

      - Ventilation holes large enough to ensnare a hamster’s paw

      - A quarter-turn friction lid that warps and can unexpectedly pop open during use

      - Inexpensive plastic materials

      His product line developed to tackle these concerns:

      - Roam – tackles all these issues with a two-millimeter paw-protection ventilation pattern and a two-step locking lid that secures pets inside.

      - Halo – an orange ring that attaches to the ball for carrying it, allowing you to walk your hamster.

      - Burrow Bricks – launching with the new big-box retail partner. Burrow Bricks are transparent three-by-three plastic squares that snap together to form hides, mazes, and enclosures, akin to LEGO for small animals.

      Happy Habitats currently holds two utility patents, both granted in 2025—one in February and the other in November. According to Ethan’s LinkedIn post, he established the company in October 2019 and filed provisional patents in 2021. Although the process took years, the protection is significant. A utility patent safeguards functionality, not just appearance, preventing competitors from legally duplicating the essential innovations.

      As Ethan put it, securing market share in a niche area makes your utility patent particularly appealing if a competitor seeks to acquire your business, as it grants the buyer sole rights to produce the product.

      Building a Product Business Through Strategic Collaborations

      After conceptualizing his idea, Ethan joined an entrepreneurship incubator at Wake Forest, which provided early funding and facilitated the formation of his LLC. He then pitched his concept to P9 Design, a product design firm in Edgewater, New Jersey, recognized for collaborating with major consumer brands like Honeywell, OXO, and S’well.

      P9 Design agreed to partner with him as an equity collaborator. Currently:

      - Ethan, his father, and P9 Design each own a third of the business.

      - P9 contributed design and engineering as sweat equity.

      - Their relationship has developed into a consistent weekly collaboration.

      Ethan’s outlook on relinquishing equity is: “Money is necessary now, but equity is what expands.” He pointed out that by the time many entrepreneurs sell their businesses, their ownership typically drops to about 7%. Trading equity for a high-caliber partner early on can often be worthwhile.

      Manufacturing is conducted in Mexico through a contact Ethan made via a speaker at his university incubator—a third-party introduction that evolved into a lasting production partnership. The product molds are manufactured in China and shipped to the factory in Mexico. This logistics setup caused initial complications, but the operation now operates on bimonthly production cycles.

      Startup Hurdles: Manufacturing, Packaging, and Pricing Errors

      Ethan humorously remarks that “everything that could go wrong, did.” He was not overstating.

      - Manufacturing delays: Molds produced in China were stuck outside the Port of Los Angeles for over nine months during COVID, completely halting production.

      - Packaging issues: A supplier switched to cheaper materials
