A bird cage with dimensions of 46.5x45.5x102 cm is suitable for small to medium-sized birds like budgies, lovebirds, or canaries. Here are some tips for setting it up effectively:

1. Perches: Add several perches at varying heights and diameters to encourage climbing and provide resting spots.

2. Toys and Enrichment: Include a variety of toys, such as swings, foraging toys, and chewable items, to keep your bird entertained and mentally stimulated.

3. Feeding Dishes: Set up multiple food and water dishes, placing them at different levels to encourage movement and exploration.

4. Hiding Spots: Incorporate small shelters or covered areas where your bird can feel safe and secure.

5. Cleaning Ease: Opt for a cage with a removable tray for easy cleaning, and maintain a regular cleaning schedule to ensure a healthy environment.

6. Placement: Position the cage in a well-ventilated area with indirect sunlight, avoiding direct sunlight to prevent overheating.
