The a&e extra large flight bird cage exceeded my expectations in its quality, sturdiness and ease of construction.  Our two budgies (Snow and Jay) could not be happier!  We got this cage because we had had our two budgies about a week and they were getting along so well with each other, but would occasionally flutter their wings very rapidly and try to fly inside the tiny cage, but hit the sides with their wing tips quite often.  -  It quickly became obvious to us that they wanted to do some actual flying.  -  We have had the new cage (I calculated it has almost 45 cubic feet of space) for only three days so far and already the budgies are so happy and we have been surprised and delighted with what incredibly good flying athletes these little budgies are when they have enough space!
