We had an unusual patient today. A semi-truck driver brought us a female opossum-- from Brownsville! Poor thing (the opossum, that is) could not even stand. We surmise she has an injured back and is not able to use her back legs. Because we have no way of taking x-rays, we called the zoo and they are willing to see her tomorrow--if she survives the night. She has not passed any fluids or solids yet, but the rescuer told us that she went quite a bit (solids) on the ride here so that's a good sign. She weighs 244 grams which is about the same as a juvenile pigeon. We are thankful the driver was able to find us and drop this girl off. We'll give her some meloxicam and feed her liquid insectivore food. Note her interesting tail. She also has very sharp teeth.
Opossums are North America's only marsupial. They are found statewide except for the arid Trans-Pecos and Llano Estacado of the Panhandle. Opossums as a group, are among the oldest, most primitive mammals of the New World. Some scientists call them "living fossils" because they have survived relatively unchanged for at least 50 million years. They are cat-sized mammals with a pointed snout, grayish fur, small ears, and long, scaly tail. It can use its tail to hang from tree branches and it has paws with opposable "thumbs." Their chief character is the marsupium or pouch that develops on the abdomen of females. One species occurs in Texas.
They have an eclectic diet and will eat both plants and animals including rodents, young rabbits, birds, insects, crustaceans, frogs, fruits and berries and vegetables.
