Sugar gliders are nocturnal marsupials increasingly kept as exotic pets. Their complex social, dietary, and environmental needs are frequently misunderstood, resulting in significant welfare compromise in captive settings.
Sugar glider welfare in captive settings is frequently severely compromised due to misrepresentation of their needs at point of sale and genuine complexity of their requirements. Social deprivation in singly or sparsely housed animals causes the self-directed behaviours (over-grooming, self-mutilation) associated with extreme stress. Nutritional disease from inappropriate diets causes metabolic bone disease, liver disease, and premature death. Their nocturnal activity pattern means that appropriate environmental stimulation must be provided at night when human owners are typically asleep. The combination of social, dietary, and environmental complexity makes sugar gliders entirely inappropriate pets for inexperienced exotic animal keepers. Welfare organisations increasingly advocate against their keeping as pets and for specialist rescue provision for those already in the trade. Their welfare needs cannot be adequately met in average household settings.
