In hot weather, it is important to check water bowls, as it is amazing how quickly they can dry up - you need to check several times a day, particularly with small bowls.  Also, you can use the material that gardeners use to protect crops from high winds, to shade flights and aviaries.  Good polypropylene woven material that is available in garden centres makes ideal shading and can be secured with little wire hooks made from common galvanised garden wire.  Why not visit your local garden centre?
