The cage has plenty of room for a Severe Macaw, and the dome top design is the only way to go for maximum space. The only problems were with shipping and missing hardware from the package. After two re-orders the missing screws and cage parts were finally delivered; that being said the customer service at Wayfair is excellent and resolved the issues as quickly as they could. Also, there are no instructions and though much of the construction is straight forward- there might be a problem for the novice. Having priced many cages, this model is a great deal.
