## Overlaps & pitfalls
A pet house could combine materials (e.g., wooden frame with textile cover), but the primary material determines classification. The main function (shelter) is shared, but the defining trait is the **material type**. If multiple materials are used, prioritize the dominant structural material. No option clearly takes priority—choose based on the product’s **main construction material**
