Title: On a concrete surface? Stay away!
Review: If you're planning to this house on cement, please for the sake of your pets, get something else.I've had this for less than a year, and the regular movement and bumping of my dogs has worn four neat quarter-sized holes in the base of the house.Also, when water drips on the roof, if follows the curvature of the plastic and comes inside the house! It's not as snug as it appears.Doors or flaps do not fit neatly onto this thing, and because it's plastic, screws can have a hard time holding. Do yourself a favor and look at your other options.
