The habikat sucks. It should be designed less curved, because it
lets in a lot of outside air. And insects.  The parts that come in
contact with the window frame shouldn't be so ridid. Another defect
is the plastic "windows"; they really should be something that
won't curl or buckle when weather conditions change. I have one,
and one day I noticed that the plastic (or plexiglass) windows
weren't flush with the inside part (held in place with only
adhesive strips) and when the plexiglass curled inward a bit, it
left enough of an opening that one of my cats could have pulled it
off enough to get outdoors. In the time I've had it, I've removed
it in the summer, and in the winter. I won't put it back in at all
now. If I were to do something like this again, I'd design one
myself.
