We made this pallet cat barn using four full pallets to make the sides, back, and roof. We stuffed all of the pallets full of hay for insulation to keep kitty warm and to keep the wind out.
Pallet Cat Barn could be made even to help the stray animals in the wintertime! :)
This is a great idea, and a kind one too if you wanted to help stray animals have a shelter from the elements. Here's an idea for a Cat Patio.
