I'm adopting a dove or two very soon, and I had picked up a 30" Length x22" Width dog cage, hoping that it would be large enough. However, when it was fully assembled, I was disappointed with it's size. An ad on craigslist is offering a 4' Heightx2'Widthx1'Depth cage. Would this be large enough for 1-2 Ringneck Doves? It's the same price as the dog cage and I can easily refund that. If not, what dimensions would be appropriate? I am looking for an indoor cage. Thanks!
