Jasmine 5 Hi there, sorry I do not speak Japanese. I read some of the reviews here through Google translate. I found out about Hoei cages on Instagram, because I often saw the cages on some bird accounts I follow. I finally figured out this particular cage is called Hoei Heartful Carry, and that I could order it from Amazon Japan.I have had many bird cages and travel cages over the years, but none like the Hoei Heartful Carry! I have caiques and conures, but it sounds like this cage was designed for smaller birds (java sparrows to cockatiels). So, I would not use this particular cage for extended trips, but it's great for a quick trip in the car.Pros: Sturdy wire construction, no flimsy bars. Removable wire grate to separate birds from their droppings. Secure food dishes. Handles on top. Clean look. Easy to store. Easily fits in car seats and pet strollers!Cons: I wish it had a door that opens to the side, instead of a drop-down door. (It makes going in and out more comfortable for the birds, because their tail doesn't hit the door and they don't have to walk on the narrow bars.) Bar spacing is a little small for larger birds (but I know it was not intended for larger birds). My big white-bellied caique gets a little anxious about walking on the door, because his big feet get caught up on the wires. A slide out wire tray and floor pan would be really nice....Pictures show my big caique (weighs ~190g, and yes he dyed himself pink today); Hoei Heartful Carry compared to the white Prevue Hendryx Travel Bird Cage (commonly available in US), and the Celltei Pak-o-bird Small backpack; and showing how the Heartful Carry fits in a double stroller without protruding.**I would order two more, but at this time they no longer ship to the US.**Please, Hoei, make a Heartful Carry XL and come to the US? :)
