Animals like us humans are creations of God or nature as one would like to call the Creator. They too have senses, feelings and emotions. They too have life and soul in them. Caring for stray animals and birds by providing them adequate food best suited to them is a great way to carry out the service to the animals. If you are successful in feeding animals, thank your good deeds because animals have a very strong sense of etheric smell and are receptive to the energy of humans.
