A parrotlet cage should measure at least 24 inches x 16 inches x 16 inches high, or 30 inches x 18 inches x 18 inches high.
Of course, the bigger the cage, the better. Birds aren’t born to be cooped up. Even these tiny parrots need space to play, exercise, and stretch their wings—especially since they’re so active! Owners say that these birds constantly move around, and only seem very comfortable in cages designed for larger birds like cockatiels. It’s always better to err on the safe side .Besides; the parrotlets will have to share their cage with their numerous paraphernalia: toys, perches and feeding dishes.
So the bottom line is to get the biggest cage you can afford, or be prepared to train your birds so they can be set free in the room for long periods of time.
Location of the Cage
The next important consideration is where to put the cage. Never put it under direct sunlight. The cage must have a shady spot where the parrotlets can retreat when they feel warm or feel they need to hide. For the perfect mix of shade and bright light, you can get a full spectrum avian lamp. Or, you can place it across the window, out of reach of the sun’s rays but still at an angle that gives it a good view.
Never put the cage in an isolated area like corridors. Birds are social creatures and they will want to interact with the family members (this is the only way they’ll get used to humans and feel part of their “new flock”). You can also place a radio near the cage so the birds can still get stimulation even when everyone’s at school or at work.
A good choice is the corner of the living room or den, or in the dining area. Avoid kitchens since the gases emitted by heated Teflon can poison birds.
Cleaning the cage
Get a cage that has a removable tray so it’s easier for you to throw away droppings or food scraps. Line this with thick kitchen paper towels or any absorbent paper. It’s not recommended to use old newspapers, since the ink can stain feathers.
You should give the cage a thorough cleaning at least once a week, using a mild bleach and water solution. Don’t use soap or any harsh cleansers, which can stick to the metal and irritate your pet’s skin.
