ns based on transparent, comparable welfare metrics. Interspecific Scaling The Welfare Footprint Framework (WFF) uses a universal metric—time spent in affective states of varying intensities—to quantify welfare impacts. Because affective experiences such as Pain and Pleasure lie at the core of sentient experience, this metric provides a common currency for evaluating welfare across contexts, life histories, and even species. It holds the potential to compare welfare burdens in a biologically meaningful way across diverse taxa, including humans. However, applying a universal scale introduces two critical challenges: (1) differences in hedonic capacity across species, and (2) differences in time perception. Hedonic Capacity and the Use of an Absolute Scale Different species may vary in their hedonic capacity [12,13] —that is, their biological potential to experience the intensity of affective states such as Excruciating Pain or Blissful Pleasure. These potential differences may stem from divergences in neural architecture (e.g., complexity of nociceptive systems or limbic structures), cognitive capacities (such as awareness, memory, or reflective processing), or evolutionary pressures that shaped how strongly different organisms are motivated to act on affective cues. At present, however, scientific knowledge on interspecific differences in hedonic capacity is limited and inconclusive. While there may be neurological, cognitive, or evolutionary reasons to expect such differences, questions about the nature and magnitude of these differences remain among the most intriguing and ethically significant in biology, neuroscience, and philosophy. Given this uncertainty, the WFF adopts a provisional but transparent convention: affective intensities are defined as absolute,
