The relation that you develop with an animal is lifelong and rigid unlike of that what you build up with a human. This is because the innocence in animal's eyes pushes you to become a better version of human you already are everyday.
Those having pets would be able to explain better that the relation they hold with these animals are priceless. Animals respond back with all their love and affection and would make sure that no harm reaches us. Whether it is birds or animals, pets have a special bonding with their parents and also with the people they feel care for them.
When whole world turns their back on you, you have a an innocent soul waiting for you to give it a chance to kiss you, hug you, listen to you, heal you, and love you without any condition.
All animals should be respected as it's species is and not humanize or anthropomorphize it. Understand the habitat, temperaments, behavior and exercise your love and care accordingly. If this is not taken care of the animal/pet becomes aggressive and turns the other way and it also damages them psychologically.
Example : For a dog you ain't mom or dad you are the leader of the pack, pack because they are evolved from wolves. So be a leader and lead the pet.
I urge people to follow this to have healthier, happier and profound relationship with your pet.
