I love the size, and its very well built, strong. Im sure it could hold any type of bird safely. The 1/2 space between the bars is very hard to find in a large cage/aviary like this. Lots of doors. The only con I have is the doors aren't made as well as the cage itself. Also they literally fell off before I did a bit of tweeking on each one. But the cage is well worth the price. Delivery was fast. Assembly was easy and my Gouldian Finches love their new aviary. This thing is BIG! Very happy with this purchase!
