308 views

Cats may avoid eating shrews because shrews excrete a pungent odor through their skin glands, which is thought to be a deterrent for predators. Additionally, shrews can carry toxins in their bodies, making them less appealing or even harmful as prey. This natural defense mechanism effectively protects shrews from being a common dietary choice for cats, despite their hunting instincts.
