Next weekend, I'm starting to build my first C&C cage. I am able to fit a 2 x 8 for my two bunnies to share. My question is, are windows okay? I have the obstacle of two windows, but I'm thinking of resolving this by draping a section of fleece over part of the cage during the winter and keeping the window blinds down in the summer. Our home is moderately temperatured, but I am worrying about the windows. Is this okay?
