Can I afford medical treatment for my pet from an exotics or small animal vet?
All 60+ kinds of opossums are solitary and should be housed separately. Even though they may be kept together in one tank at the pet store, that is because they are young and don’t become fully hostile until they reaching maturity. And the older they get, the more hostile they get towards each other and the more likely it is for tank-mates to attack or kill each other – even if they have been getting along.
