The article analyzes the problem of incorporating the welfare of pets into municipal adaptation plans (MPAs) in Poland. MPAs constitute a key instrument of urban policy for climate adaptation; however, in practice they focus almost exclusively on the needs of humans and infrastructure, overlooking pets as a distinct category. An analysis of 21 MPAs adopted in Poland in 2025–2026 demonstrates that only three include direct references to pets (e.g., drinking stations, green areas, relocation of a shelter), indicating the marginal consideration of their needs. As an analytical framework, the authors propose the concept of the limited legal personhood of pets, which entails recognizing their interests (e.g., a right to welfare) and their indirect representation by guardians. Adopting such a perspective could lead to more inclusive urban policy design that accounts for both human and non-human inhabitants. In the prescriptive section, several directions for reform are identified: integrating pet welfare into climate risk assessments; incorporating their welfare into the strategic objectives of MPAs; developing animal-friendly infrastructure (e.g., shaded exercise areas, access to water); and implementing educational measures.
