Pets do get lonely during the day when we are not home or if they are in a cage in a shelter.  Lots of people leave the radio or TV on during the day to keep their pets company. This is OK, but dogs and cats do not really get any pleasure or comfort out of it. It has been proven that animals do respond to music.  Classical music is what animals tend to respond to best. There are companies that sell music that is especially designed to calm and comfort pets. So when you leave the house in the morning, don’t just leave around dog or cat toys, put on some soothing classical music to calm and comfort your pets while your gone.
