Modern welfare science has moved beyond preventing negative experiences to actively promoting positive ones, recognising that genuine welfare involves pleasure, engagement, and flourishing — not merely the absence of pain.
The shift toward positive welfare represents a fundamental rethinking of what it means for an animal to be doing well. A life that is merely free of obvious suffering is not the same as a life worth living — it may involve chronic boredom, social isolation, lack of agency, and inability to express species-typical motivation. Truly good welfare requires positive experiences: genuine interest, social engagement, physical comfort, play, and the satisfaction of natural drives. This is not a luxury standard but the minimum that genuine care for animal wellbeing demands.
