Disability rights philosophy offers important insights for animal welfare ethics, particularly regarding the value of lives with limitations and the ethics of modification versus accommodation.
The disability rights movement offers valuable critiques of utilitarian welfare frameworks that equate welfare with function. Animals with chronic conditions or impairments can have rich, meaningful lives that deserve protection. The decision to euthanize a disabled animal requires careful welfare assessment rather than assumptions about quality of life from a non-disabled perspective. Conversely, the capabilities approach that asks what a being is able to do and be — applied to healthy animals in poor conditions — strengthens the case for welfare improvement.
