It needs to be big enough for the parakeet to stretch its wings and fly form one side to the other. The cage also needs to have intersecting bars enabling the parakeet to climb. There are many different cages to choose from. They can be basic and inexpensive or elaborate and quite costly. There are cages to meet all preferences and budgets.
Liners containing grit necessary for birds are available for the bottom of the cage.
These make cleaning easier, but paper toweling cut to size works just as well as long as grit is provided in another form. Grit embedded perch covers are good to use in a parakeet's cage. Besides providing grit to the parakeet's diet, the rough texture will help keep its nails and beak worn down. According to the book, the cage and uncovered perches should be cleaned with hot water each week. Covering the cage with a light weight material at night will help make the parakeet feel more secure.
