After 12 years of farm house renovations, I had some old windows stacked against a shed wall. Just one of those things where you can't bring yourself to put them in the construction dumpster.
This weekend it was a brilliant sunny day but cold and I thought-- Cat Greenhouse! Why not. Picked up a couple cheap hinges and set the two "window tents" side by side on the south side of the chicken coop, and tacked on some tank insulation to cover up the ends. (Will go back and make that look neater, I just wanted to test the concept and see whether the barn cats would even go near the thing). They LOVE it. It's like 70 degrees in there, despite <30 deg temps outside. All the water troughs had a thin skim of ice on them this morning, while the water dish in my Cat Greenhouse was warm.
Like I said, I'll go back and re-do the insulation on the ends, so it doesn't look quite so trashy , but thought I'd post this idea in case any of you have old windows lying around and barncats to keep warm.
This weekend, I'll put a pallet underneath, run a strip of 1x1 along the edges to prop the frames against, so they don't slide outward & off the pallet. This will keep the wood frames --and kittehs--off the damp ground and make them easier to move around. And in the spring we can put some planting containers in there, and have early lettuce and herbs!
(Lordy, nothing like putting a picture online to make you realize that the chicken coop *really* needs a coat of paint. )
