Žaltys (literally: grass snake) is a household spirit in the Lithuanian mythology. As sacred animal of the sun goddess Saulė,[1] it is a guardian of the home and a symbol of fertility.[2] People used to keep it as a pet by the stove or other special area of the house,[1] believing that it would bring good harvest and wealth.[2] Killing žaltys was said to bring great misfortunes upon the household.[1] If žaltys was found in the field, people gave it milk attempting to befriend the creature and make it a sacred houseld pet.[3]
