Very disappointed. It assembled ok except for the side outer shelf which would not fit between the brackets so I had to saw/chisel one side so it would fit. And after one week the supposedly removable inner shelves have started to warp so I’ve removed the top as that’s the only way to get the shelves out and will apply a protective coating. More importantly our 2 cats won’t go in it. I don’t know if it’s the fir wood smell or what. The bottom front door is quite small so I may need to enlarge it and I removed the top large door to allow more air flow. I would probably just return it but I’ve discarded the box as I thought it would really work for our cats when I assembled it.
