I placed the Outdoor Kitty House between a wall and a bush so it would be secure from the wind. We had a very windy day this week and the house stayed secure. If you place it on a patio you could secure it with Velcro strips using heavy duty double sided tape to secure the Velcro to both the house and the patio. You could stake the house to the ground if placing on dirt or on the lawn providing you put grommet holes into the house at the bottom and then you could stake it to the ground similar to a tent. There are two door flaps that Velcro onto the openings and can be removed. They are great for keeping the cold air out and work similar to pet door flaps so the cats can easily get in and out. When the weather is nice you can just leave them off. There is a nice cushion that is easily removed for cleaning and cushiony for the cats. I would recommend a blanket for added comfort and placing the house on top of a thick mat either rubber or carpet to help keep the cold from coming up through the bottom in the winter.
