Listing here some links to home made shelters and feeding stations for cats.

Remember, most cats have somewhere they have already picked out that is warm enough and dry, or they wouldn't stick around! Sometimes providing a shelter does more for the caretaker than the cat!
Thank you for caring for these helpless ones!
