Wild animals and domesticated animals differ in behavior due to their natural instincts and how they have been raised. Wild animals are typically more cautious, independent, and have strong survival instincts as they need to find food, protect themselves from predators, and navigate their natural habitats. On the other hand, domesticated animals have been bred and raised by humans for specific purposes such as companionship, work, or food, which can result in behaviors that are more docile, social, and reliant on human care and guidance.
