Sometimes our pets are very friendly. You can cuddle with them and they will talk and sing. However, sometimes they really would like alone time. Just like humans. I have found that my parrot will byte and become aggressive when they want to get put away. So I put them back in their Parrot Cage. This is their home and they feel more comfortable there than anywhere else. So when picking your cages for your birds remember that your bird enjoys his quiet time and room to move. Cages come in all sizes. I wouldn’t necessarily put a small parrot in a big cage either. Size the cage to your bird. They are like feet and shoes.
