The Short-Tailed Opossum is an escape artist, and must be kept in a secure enclosure. A 10 gallon or larger aquarium with a secure lid or a narrow-mess wire cage work well. Provide corn cob, Care Fresh litter, or shavings (though not cedar) for bedding and a nest box with some nesting materials such as cotton or shredded paper. For exercise and entertainment they will need things to climb on such as branches, ropes, or parrot ladders, and you can also give them a small hamster wheel. For some fun you can include such things as clay flowerpots, pvc tubes, and other places for them to hide. They need a draft free warm environment. Keep the temperature between 68° - 88° F. and at least a 50% humidity, a little on the warmer side is best for mothers with babies. They are neat clean little critters and will usually pick a corner of their enclosure for a bathroom. They can even be trained to use a litter-box, which makes cage cleaning much easier. Short Tailed Opossums are basically odor-free and their cage only needs to be cleaned about once a week.
