The PINK one is really nice too, but we figured "the girls" drew enough attention without the bright color and the darker one would be much easier to keep clean. The idea that they can be free inside makes them very comfortable to be in the mesh area or inside the "house" area. Sometimes one will be inside laying down. They also have covers for them I believe. I've made a mosquito/bug net for ours. At home its opened for them to use as they please. The older goes in there when it thunders and as soon as I say " time for a walk", both automatically go inside and are ready to go !! Its been fun !
