We have the same couch! LOL.

And yes, it is always recommended to quarantine your new ratty in a seperate building, such as a friends until you make sure that your new little one isn't sick. If doing so is impossible please at least keep them in seperate cages behind closed doors, seperate rooms.


If they've seen eachtoher already, chances are, they've already spread diseases to one another. So watch them carefully.
