Yes.
I have two of the 48x24 sliding front door glass cages.
They are very nice and the delivery was pretty cheap (as long as you are in one of their self-delivery areas).
They don't have tops, but the screen tops that they sell (separately) are
nice heavy metal mesh [easily supports the cat's weight] and the mesh is
wide enough to not seriously block UV light (I use mercury vapor bulbs).
I haven't actually seen the "grey" acrylic ones in person, but I do think that
the next one I buy will be out of the acrylic, just because the glass ones are so heavy.
