In my old apartment I covered 3 sides plus the top in the winter because of the draft (she has a C&C cage). Now, there's no draft, but I do cover the top because she's such a shy little girl and seems to feel safer with a top over the cage.
But, I'm wondering, am I doing a disservice to her by covering the top of the cage? Is this "enabling" her huffiness, or is it the opposite - is it good for her since it makes her feel more safe?
