Thank you very much for the many likes! I will also include the bird's nest in the second photo (new, unused, unopened)! You can use it with a heater. HOEI medium-sized birdcage, with perches and food containers. - Brand: HOEI - Type: Birdcage - Accessories: Perches, food containers, heater - Size: Medium - Color: Black/White Please note that the size is approximate. Height 38.5cm Width 27.5cm Depth 35cm You can easily clean it by sliding out the bottom tray. Heater operation confirmed. The heater has some stains. The included sand perch fits perfectly, so I will ship the sand perch unopened. Perches are sold for a few hundred yen at pet shops, so I recommend purchasing a new one. One perch has been cut for length adjustment. Thank you for looking.
