The cat house seems to be prefabricated with quality wood products.  There were no blemishes in the wood that I noticed.  One small door did have a gap which I will need to resolve before winter, but everything else assembled nicely.  Extra screws were included for those more frequently used and dropped. One item was particularly noteworthy.  For the braces supporting the shelves, the holes were angled for ease of installation.   This may seem small, but it did save time and frustration during assembly. This indicates to me Wayfair’s focus on customer satisfaction. I would highly recommend this product.  Will be purchasing another one today.
