Margaret, I feel honored that you used our cat houses on your outdoor enclosures page. I'll have to take some more pics, because we covered both of the little houses with vinyl to add even more warmth/insulation/protection from cold air/and waterproofing .

This is just one with Ivory ontop the roof, but I'll take some better ones tomorrow and post them.
Nice pics. That was a good idea to add vinyl. I will use the new pics coming up when I edit that page. I might need to do a second page about all you did, including finally getting Cheddar indoors. If you feel like writing a draft about your experience from start up to now, that would be good. Otherwise, I'll get around to it one of these days, and hopefully not a whole year later.
