While Tikeyas Mom has a good point, any reputable rescue group or animal shelter will isolate incoming animals until their health exam is completed and the animal has a clean bill of health. These organization usually have to meet standards and guidelines in order to remain in business. Besides, the absolute last thing they want is to adopt out a sick animal and have their reputation ruined. They could possibly reported to a humane society, city or state oversight organization and/or have a damaging story printed in the newspaper. They would end up being fined and/or shut down and the animals confiscated. This should not happen in a good organization.

You DO have to be careful where you go and it's pretty easy to tell a reputable place from the bad: Ask around, what rescue organization or group did friends or family get their pet(s) from and what did they think about it? If you don't know anyone who has adopted a rescued animal, you can tell just be looking at the facility if it's a good one: is the kennel area and cages clean? do ALL of the animals/rabbits look well kept, well fed, bright, alert and playful? is their fur clean, soft, esp the back end? are the eyes clear?

BY going to a reputable rescue group or animal shelter/humane society with your bunny and having them meet before you take the 2nd bun home is your best chance at getting a good match. Yes, when you get the new bunny home they might squabble for awhile but that will stop eventually. Rabbit rescue groups can be found on the web and most have ties to professional rescue organizations so they are safe and well-run. Don't let the nay-sayers here talk you out of letting your bunny pick his own friend.
