Cage sizes and diet?

Question
Hello again, I was wondering if you knew how big a cage for a breeding female mini rex should be? also should they have a special diet before being bred, during pregnancy and while nursing? also when I introduce them where do I do that and how long should they be left together? I am aware I have to watch them as they can start to fight.

Answer
as big as possible mine ar 18" high and 3 feet long with a sleeping compartment.
no special foods just feed and water as normal.
always put the doe to the buck in his cage if you put the buck to the doe she will fight.
mating should take place immediately and it will last about 30 seconds.
then remove the doe straight away or she will try to bite the buck
goodluck
dave.
