How to set up a parrotlet cage
Give your bird room to stretch its wings.
Parrotlets will like some space, so a cage that's about 18 inches (46 cm) on each side and 20 inches (51 cm) high will work perfectly fine. You can choose a larger cage if you like, but there's no need for it to be huge.

Choose your answer from:
(1). The bird needs a spacious cage as well as a comfortable place to sleep. This is especially important for older parrotlets with short and whiny backs.;
(2). Choose a cage with narrow bar spacing. Parrotlets can get caught between the bars of cages if they're not properly spaced.;
(3). If your bird needs to go outside, get it to the ground first. If possible, get a safe floor for your bird's cage.;
(4). A cage that's 12 inches (25 cm) high can suffice. Make sure any elevated surfaces are safe for your bird.;
