I bought my Cockatiel a new cage last weekend.
So much better than the old one! Also got her some new toys to fill some space. I'll have to buy more to put on the top. ^_^
She loves it! She spends more time in this one than the old one, and she utilizes all of the toys, perches and ladders. I don't have to chase her down to get her inside the cage for bedtime anymore.
