A parrot needs a cage it can call ‘its home’ where it feels comfortable, safe and joyful. So when you choose a parrot cage you do not only need to make sure you will be able to move and clean the cage but you also need to consider the well being of your bird.
Bird Comfort
The size of the cage, its bar spacing and thickness depends on the size of your parrot. A cage must be large enough to enable your pet to spread both its wings freely and hop around in the cage. Make room for toys and other stuff in your bird’s cage to enhance your bird's environment. The larger the cage size, the better.
It would be advisable to look for the largest cage with 1/2 inch spacing. Ensure that the bar spacing is smaller than your bird's head to prevent it from becoming trapped in the bars. A good space for medium birds is 1 3/16, and for larger ones, 1 3/8 is good. Horizontal bars allow birds to climb around the cage. Also, the strength of the bars is especially important for big parrots.
Place the cage in an area of the house where your parrot can see and interact with the family. It is best to place the cage in an area with a partial view out a window so that your pet can avoid unwanted/frightening views unless, of course, the view is of a quiet garden offering green and trees.
A locking mechanism should be present on entry doors and feeder doors, to prevent accidental escapes. Parrots are highly skillful in finding ways to get out. Quick Links (the-c-type links) can be used to prevent parrots, from escaping. Larger birds may require padlocks. Some cages provide locks not only on the door of the cage but also on the back of the dishes.
The cage should have neither sharp edges nor blobs of weld or spots of rust which can cause metal poisoning to your bird. Of course it will need to be strong enough to withstand the most powerful beaks.
Easy to clean
The cage should have easy to clean, removable grids and litter trays with removable seed guards to avoid the mess outside the cage. You will need to consider a cage which has the hardest and strongest oven baked powder coating which will withstand the everyday repeating cleaning process.
Easy and safe to move
You will need to move your bird cage for cleaning and to custom your parrot to accept changes. For those reasons you need to make sure the wheels of your cage will not come off. Cages with small rubber/plastic type wheels very often come off after a week or so as the wheels cannot support the weight of the parrot cage. You need quality designed very smooth, easy roll wheels that are heavy duty and practical with no hard plastic, so no scratches to your wooden or tiled floors.
Birds at Play
The cage should provide not just a secure home for the bird but also a great place for the parrot to play and to hang out Choose a parrot cage which offers a removable play top and a landing platform, so, there will be no need for you to buy and accommodate a separate play stand. The landing platform is very useful when you are trying to get your parrot back into its cage.
