Don't know who it's by...I bought it second hand from someone who was getting a bigger cage for their African Grey... It's a great size for my IRN, at
26" x 24" x 34". It has the main big door, a smaller upper door, and a top that opens upward... Very heavy duty solid cage. We're happy with it, or at least me and the birds are (Tiki travels over and boots Pippin out for a while easch day)...DH thinks that, with the seed (POOP) catcher, it is too big. What does he know?
I have to add, too, that both Tiki's and Pippin's cages are only ever closed for bed time and when we are out... when we are home, the cages are always open.
