Easy to assemble, solid construction. 2 of my cats have tested it out inside and were happy to sit in it for a nap. Haven’t tested it outside yet in wet weather. Not sure what sort of padding to put in it for outside use that would be waterproof. Think a second edition could use a few design tweaks. The entrance hole could have been narrower and shorter to offer more protection to cat from rain and wind when house is outside and a waterproof base pad added to inside of house for more cat comfort. Overall I think cat villa is solid and sturdy and a good size and light enough in weight to put up high in and outside cat enclosure and offer shelter and a place for a cat to sit on top of it.
