A shrew’s diet consists of pretty much everything and anything. Shrews have to eat their weight in food every single day and if they don’t eat within a few hours they can die. They prefer to eat insects, slugs and snails, and earthworms. As well as seeds and nuts from trees. But they are notorious for attacking and eating prey much larger than they are. They’ve been known to eat snakes, mice, small birds, and in the picture above even lizards. When they bite into their prey they excrete poisonous saliva into the wound that paralyzes the animal. Unfortunately for the prey, it doesn’t kill them right away. Instead, it keeps them alive for a few hours. This allows the shrews to keep the meat fresh so they can eat it later.
