No offense Jen, I think you share a lot of great info, but most of those things are worst-case scenario. Can they happen, yea. Will they, most unlikely. Especially when it is a male and female housed together.
I have housed males together and females together. Never a real problem.
With the males, when they reach sexual mayurity, they may try to breed each other. I seperated them at that point.
With the females, they were mostly fine. I had anywhere from 500 to 3000 grams together. They were all fed in seperate enclosures and it worked fine.
This is speaking from experience, not from what I've read and seen. Most people would not suggest it, and neither would I, but when you are in college and short on space, you do what needs to be done.
I keep them all in racks now, seperately. And I still have all the animals that were once housed together, all still alive and eating like champs.
