How to prepare for a parakeet?!?!
first thing is make sure you have a cage and food and water. :)
Also when the parakeet arrives give it a day or two to get used to it's surroundings before you start handling it..else you'll just stress the bird out.
Think about where in the house you are going to keep the cage, they are very sensitive to drafts. Make sure you get a cover for the cage, and always change there water
