There are several hypothetical reasons (or a combination thereof) why your pet cat has a penchant for catching shrews and small furry things – even though it might not kill it:
2. To please you: a way to earn their keep even if you couldn’t care less about the shrew to begin with. Your cat knows that one shrew covers this month’s rent.
3. Education: especially if they bring it back alive. They may be trying to teach you the way a real predator hunts, none of that insecure macho-gun stuff.
4. Their first time: Cats learn a lot about particular prey as they mature. This may have been the first time your cat has tried to kill a shrew and was unaware of the unpleasant surprise. Shrews obviously don’t taste as good as they look.
