you should look into maybe a cage simular to this...

that way you can buy both cages in one instead two diff ones it could save you some money in the end... plus they last a long time... and have breeding doors.
something for you to consider...
also if you tell us your budget i am sure some people will be glad to throw some ideas your way...
