This little female is an RAF male x a std female of my breeding (Little Sugar x Ryerson)
She's the first heavily marked kit I've had. Sadly, her father passed away.
Personally, I've only tried it a few times and it didn't work out. One pair almost couldn't live together again. The time it did work, it was only after putting them in a large carrier together, carrying them around, and keeping them there for a day.
If you can keep from taking it apart, that's better. You need a screwdriver and the pieces can get lost. The top doesn't come off as it looks like it could-- the whole thing has to be disassembled.
I've separated before. Since they haven't always been together it shouldn't be do stressful. If they do go separately, separate them before they leave to get them adjusting to it. They may not even miss each other but you could put the cages closer together.
