Do animals get jealous

Why do dogs get jealous
It's all about deep instincts. Because of them, the dog always builds a hierarchy at home, including all animals and people.
In addition, the dog will drive away everyone who stands below her from the owner - the source of attention, affection and treats.
How jealousy manifests itself in cats
Cats can become jealous when they feel that the intensity of interaction with them has decreased.
They show signs of jealousy when you start paying more attention to another animal, laptop or person.
This could be the arrival of a new family member, such as a newborn baby or puppy.
Typical manifestations of jealousy include hissing, growling, and hitting an object with their paws that cats consider a competitor.
