A new pet can be a fantastic companion, but sometimes the novelty can wear off (some pets live for a very long time). You may find that regular cleaning, feeding and handling becomes a time consuming chore. Please try to handle and play with your pet as often as possible, you will find that you will be rewarded with a much happier and friendlier pet. If you are not 100% sure that you or your children will be able to give your pet the attention that it needs then please think twice. Average Adult Size: Budgies vary in size from 5 to 11 inches. They’re not the smallest parrots – that distinction belongs to the parrotlet – but budgies are quite tiny.
