Cats don't need to be trained to use a litter box - they just do it. By understanding why they prefer to eliminate in a litter box will help their human owners not to make any mistakes in having and maintaining the cat box.
The conventional wisdom (in the Northern Hemisphere) is that the best direction to face solar panels is south, since that is generally where theyâd receive the most sunlight. However, the electricity system is not as simple as it sometimes seems, and the best direction to face solar panels may actually be west!
The optimum compass direction for a house is facing N.E. Back of house would be S.W. Generally, the most windowed area of the house is the back. In the winter when the sun is low to the southern horizion, you get optimal exposure and heat gain. During the summer with the sun more overhead you have less heat gain. You can also reinforce that winter heat gain with a large stone/concrete interior wall that is exposed to the sun during the day.
