Before considering a cockatoo as a pet,
there are a few things that you should know. First of all, they have a long life span. They can live to be 100 years old. These pets will more than likely outlive you so anyone purchasing a cockatoo should do so only if they are sure that can devote the rest of their lives to the needs of the bird.
When housing your cockatoo you can either purchase a large cage that is designed for cockatoos or you can use a perch. If using a perch it's good to keep the wings clipped to prevent injury. If using a cage line the bottom with newspaper or custom made liners. Make sure to clean the cage at least once a week to prevent bacteria. Place the cage out away from drafts and away from the kitchen. Toxic fumes from Teflon cookware overheating can kill the bird. If being given free roam of the house, make sure to keep all toxic plants and other dangers away from your cockatoo.
You can feed your cockatoo fresh fruit along with a good quality mix that is formulated for cockatoos or even a parrot mix will do. Always make sure they have a fresh supply of water always available. Cockatoos love to play. You can purchase sturdy bird toys from your local pet store.
Cockatoos groom themselves so bathing is something they do for themselves. You can fill a shallow bowl with water and let your cockatoo use it as a birdbath, but most will just enjoy a good misting with a spray bottle.
Cockatoos are very loveable and very affectionate. They will go to great lengths to get your attention. They have been known to knock things over, squawk loudly or even at times bite just to get you to notice them. Cockatoo's mate for life and if not introduced to another cockatoo may very well choose their human companion as their mate and will become bonded for life. If taken away from the person or other bird that they have bonded to, they can die from being brokenhearted.
