A bird cage with dimensions of 46x46x94 cm is a good size for small to medium-sized birds, like budgies, cockatiels, or finches. Here are some tips for setting it up effectively:

1. Perches: Provide a variety of perches at different heights and materials to promote foot health and give your bird options for resting.

2. Toys: Incorporate a mix of toys, such as swings, climbing toys, and foraging toys, to keep your bird engaged and entertained.

3. Feeding and Water Dishes: Position food and water dishes at different heights to encourage movement. Consider using sturdy dishes that are easy to clean.

4. Hiding Spots: Add small shelters or hides to make your bird feel secure and safe.

5. Cleaning: Opt for a cage with a removable tray for easier maintenance, and establish a routine for cleaning to ensure a healthy environment.

6. Location: Place the cage in a well-lit area with good airflow, but avoid direct sunlight for extended periods to prevent overheating.
