For those of you with larger bunnies..
I'm going to be building a cage out of NIC cubes fairly soon. I was wondering what you thought a good size cage for a larger bunny would be? I have no idea what breed they are but their father was a pretty large bunny so I want to make sure that I'm giving them enough space. The cage will be huge for them for awhile but I want the room to be there for when they get larger. I was going to do something like 3' x 3' x 6' so i could put in two levels.
