I purchased this triangular tent for a Java sparrow, but it's the wrong size and I haven't used it. Made by Pet's One. I bought it to store a heater, which I'm also selling separately. The size is perfect for it. I'll sell it to someone who understands that it's used. Size: Floor width (approx. 13cm) Depth (approx. 15cm) Height (approx. 9cm) The bottom with the heater pocket is removable.
