Domestic rats are highly intelligent, social companion animals with complex care needs that are frequently underestimated, leading to chronic welfare problems.
Companion rat welfare depends on providing appropriate social housing in same-sex pairs or groups, large multi-level enclosures with hammocks, tunnels, and foraging enrichment, and daily free-roam time outside the enclosure. Their short lifespan of 2-3 years makes veterinary care including pain management for common conditions like respiratory disease and mammary tumors a welfare priority. Handling from a young age creates confident, human-trusting animals with better welfare outcomes.
