What primary food sources define the initial diet of newly emerged Western Rat Snakes?

Lizards and smaller amphibians like salamanders

Newly hatched Western Rat Snakes are small and their energetic requirements necessitate focusing on prey items that are easier to capture and require less energy expenditure. Their initial diet is characterized by a high reliance on ectotherms and the very young of endothermic species. Specifically, sources indicate a strong focus on small creatures such as lizards and amphibians, particularly salamanders. Furthermore, the smallest individuals frequently target the eggs laid by other reptiles or birds. This specialization ensures the young snake can secure sufficient sustenance early in life, setting the stage for future growth before they develop the size necessary for larger prey.
