I paid to have a skylight put into the roof because it was as dark as a cave in the center of the house, even at mid-day. It had been that way ever since we first moved into the house. The original 'architect' thought that having windows on either side of the fireplace at the back would allow enough light into the interior to avoid plunging the room into darkness, but it wasn't enough. So, when I had the roof rebuilt and brought back up to code late last year I also had the contractor put in the skylight.
It's been a big hit with all the animals.
While the skylight is double-paned to keep the heat out, all the critters still love to nap under the beam during the middle of the day.
The cats in particular love to have their ears in the light, especially Lulu. Since I understand cats even less than I understand Labs, I haven't a clue why they do this.
I guess that's why we have the critters around. They keep us entertained.
