We are a breeder of tiny opossums (the size of a Syrian/teddy bear hamster) that are native to eastern Brazil.  Most frequently they are called short-tailed opossums (or STOs), but sometimes you'll see "Brazilian gray opossum", and their species name is Monodelphis domestica.  We like to call them potato opossums. The look like potatoes and their tail isn't all that short anyway. Still, we will mostly use short-tailed opossum/STO on our care guides to keep things simple.

      They are considered "exotic", but they have been bred and used in research for decades and are well adapted to the domestic life. They can thrive (with good care) as well as other small pets, though they are as different as they come. We are frequently asked what other pet they are like.  The only other pet they are like is another short-tailed opossum and even then they can be so different. They are very much in their own unique category.

but why do we breed them?

To get their care out of the dark ages:
The same outdated care guide has been copied and pasted so much its self-referencing.  Repeating it would waste everyone’s time. I’m using the science-y skills of procrastinating biology PhD student to de-jargon, organize, and share the research hidden in google-scholar-land. I don’t want to just list recommendations; I want to explain them too.

To suggest a standard:

Typically you see a picture of available babies, but nothing else: parents, set ups, nor their lineage. This is facilitating a culture of backyard breeders. People don’t know what to expect, or even that there should be expectations. We want to show what people should be looking for. We treat parents like we hope their joeys are treated in their new homes and we show it. We are also starting pedigrees that will reduce future inbreeding. I can't tell you how many times we have been asked for _ males and _ females and not if they're related.
