In reality, animals are not like inert stones. Because they have a soul, they are like human beings, sensitive to pain, sad in the face of misfortune or abandonment, and suffer when tortured or beaten.
Yes animals are sensitive to pain, to sadness, as to joy, yes they suffer. They very often express their suffering in silence. They express it in various ways, through submission, grunt, entrenchment, immense facial sadness, etc. It is abnormal, vile and foolish to ignore this truth.
Now all who claim otherwise are doing it to justify their unhealthy greed and cruel tendency to eat the flesh of animals, and take immoral pleasure in it.
The duty of the human being, whatever his social status, is to protect animals and plants, because if the human being continues his spiritual evolution in the consciousness of God under the guidance of a spiritual master, an authentic servant of God, it is the same for animals and plants. If, unlike human beings, the spiritual evolution of animals and plants is automatic or systematic, the latter can be hindered when their physical integrity is attacked, by killing or destroying them. And that, God condemns him.
It is written:
The righteous take care of his cattle, but the bowels of wicked are cruel. (Proverbs 12:10)
Know each of your sheep well, take care of your herds. (Proverbs 27:23)
Then God said: Let us make man in our image, after our likeness, and let him rule over the fish of the sea, over the birds of the air, over the cattle, over all the earth, and on all the creeping things that crawl on the earth. (Genesis 1:26)
The Lord God took the man, and the placed in the Garden of Eden to cultivate it and to keep it. (Genesis 2:15)
Thou shalt not muzzle the ox when it treads the seed. (Deuteronomy 25: 4)

But ask therefore the beasts, they will instruct you, the birds of the sky, they will reveal it to you. (Job 12: 7)
Don't we sell two sparrows for a penny?
However, not one falls to the ground without your Father's will. (Matthew 10:29)
