The Virginia opossum (Didelphis virginiana) is a marsupial weighing 4 to 12 pounds (1.8 to 5.4 kilograms) and living 2 to 4 years in human care in many cases. A basking spot near 90 degrees Fahrenheit (32 degrees Celsius) with a gradient down to about 75 degrees Fahrenheit (24 degrees Celsius) offers thermoregulation choices across the day. Food portions often start around 0.5 ounce (14 grams) per feeding for small species and scale with weight, activity, and life stage rather than eye estimates. A basking spot near 90 degrees Fahrenheit (32 degrees Celsius) with a gradient down to about 75 degrees Fahrenheit (24 degrees Celsius) offers thermoregulation choices across the day. In the wild, Virginia opossums use shelter, foraging, and rest cycles that translate into clear care priorities at home: steady temperatures, clean water, and predictable routines.
Families do best when one adult owns the core routine and others support with clear backup roles rather than improvising.

Food portions often start around 0.5 ounce (14 grams) per feeding for small species and scale with weight, activity, and life stage rather than eye estimates. A hide or shelter sized roughly 12 inches (30 centimeters) on a side gives a secure resting spot that can be cleaned and dried quickly. The Virginia opossum (Didelphis virginiana) is a marsupial weighing 4 to 12 pounds (1.8 to 5.4 kilograms) and living 2 to 4 years in human care in many cases. Water offered in a shallow dish about 6 inches (15 centimeters) across lets the animal drink without strain and is refreshed at least once daily.
What a treat is for this species
Good records beat memory: a one-line note on food offered, water changed, and behavior noted takes under a minute and pays off at veterinary visits. Substrate depth of 2 to 4 inches (5 to 10 centimeters) supports digging or burrowing where the species naturally does so and still allows spot cleaning. The Virginia opossum (Didelphis virginiana) is a marsupial weighing 4 to 12 pounds (1.8 to 5.4 kilograms) and living 2 to 4 years in human care in many cases. Handling, where appropriate for the species, should be brief, supported, and ended while the animal is still calm rather than pushed to tolerance.

Routine for Virginia opossums stays predictable: same order, same quiet cues, same gentle close to the day. Cleaning is not just about smell; dry, unsoiled bedding and fresh water reduce skin, shell, respiratory, and digestive risks.

Small, consistent improvements beat dramatic overhauls that can stress the animal and mask what actually helped.

Shopping and label reading
A typical adult enclosure might offer about 4 feet (1.2 meters) of usable length with a warm zone near 85 degrees Fahrenheit (29 degrees Celsius) and a cooler retreat near 72 degrees Fahrenheit (22 degrees Celsius). Weight checks using a scale accurate to 0.1 ounce (2 to 3 grams) for tiny animals or to 0.2 pound (90 grams) for larger ones catch trends early.
