Took in a brother/sister pair of Virginia opossum (Didelphis virginiana) that somebody tried to rehab after their mother was killed. Not sure how big they were when the person got them, but it was very early spring. Now these two are morbidly obese (male weighed in at 14 pounds, female at 11) , very imprinted to people, have never been outdoors, never learned how to hunt or forage for themselves, and they were fed a very poor diet.
For size reference, Brandi is 5’4″ and holding them against her body in the pictures.
They have also been kept together the entire time so there is the possibility that the female may be pregnant as opossums reach sexual maturity at an early age due to their short lifespan.
These two will NOT be able to be rehabbed and released to the wild.
Situations such as this are why permits are needed to rehab wildlife. It ensures proper training in care and medical needs to return wildlife back to the wild.
