About Us

At Four Trees Laboratory (FTL), we turn everyday frustrations into practical inventions.

We are an independent innovation lab exploring better solutions for home, pet care, and outdoor life. We are not limited to one product category—each project begins with a simple question: Can this everyday problem be solved in a smarter way?

Our solar-powered hiker mini fridge and warmer was developed to make outdoor adventures more convenient.

U.S. Patent Pending — Provisional Patent Application No. 64/012,725.

Our current focus is PurrFlush, a smart automatic-flushing pet toilet designed to integrate with a household toilet and eliminate the daily burden of litter and scooping.

U.S. Patent Pending — Provisional Patent Application No. 63/914,351.

From early ideas and prototypes to testing and continuous improvement, we share the invention journey and listen to the people who may one day use our products.
