Sugar gliders are marsupials native to Australia and Papua New Guinea that have become popular exotic pets in the United States. Their complex needs make them poor candidates for typical pet ownership.
Sugar gliders in captivity suffer from multiple welfare problems rooted in the mismatch between their natural lifestyle and typical pet conditions. Isolation from conspecifics causes chronic stress; inadequate diet causes metabolic disease; and insufficient space for gliding prevents normal locomotion. The mall kiosk selling model is particularly problematic, involving impulse purchases with no welfare screening. Many sugar gliders are surrendered within months. Their classification as exotic pets in many jurisdictions means welfare laws providing protection for dogs and cats do not apply to them.
