Cats! Do we need to say more? Maybe a little bit. The concept of reputation is used to pass information about someone’s behaviour without having to interact directly with that person. In other words, if someone is a bad person, you can be aware of it in advance, and also in the other way, if someone is good, it is good to know. Surprisingly, this not only applies to humans, it is also true between other animals like dogs, and in between dogs and humans (yes, your dog will tell other dogs if you are good or bad for him). The next experiment aims to study if this type of reputation knowledge applies also for cats, and if cats share the reputation with other cats, so they can know which human they can trust or which one they should avoid.
