but being a packrat, I had a lot of odds and ends to make one. I'm trying to remember it since it's been a while.
I turned a rectangular, plastic laundry basket on its side. I put a bunch of old towels down inside (in case I had to wash the bedding at some point). Then I doubled-up a couple old blankets, thoroughly covering the basket. This was followed by a bunch of old windbreaker jackets to block wind and rain. I probably put everything but the kitchen sink on it 
including one of those big Snuggie blanket things somebody gave me for Christmas.
I was worried about it being warm but once after it snowed, the (stray) cat let me put my hand in there and I could actually feel the warmth radiating from his body heat.
And that's the story of my cat shelter
