Besides mice and rats, what larger mammals might occasionally be predated by a powerful adult Western Rat Snake?
Answer
Shrews or young rabbits
While rodents represent the cornerstone of the adult Western Rat Snake's caloric intake, these snakes are characterized as opportunistic feeders. This means they will readily consume other available prey items if the opportunity presents itself, especially when they are large and strong enough to subdue them. In addition to their heavy reliance on mice and rats, large, powerful adults are documented to occasionally capture and consume other small mammals, such as shrews, or even young rabbits found within their range. These items supplement the diet, though they do not form the central pillar like the rodents do.
