There is on opinion that animals are creatures that do not have own conscious.

That animals are the instinctive creatures of the living world.

That they react only from instincts that are inherent in them by nature.

A humans has a self feeling and are able to realize themself in place where a person is and who (s)he is.

We can't know the opinions of animals on this matter - does they realise themselves who they are?

And can only make an opinion by watching them.

A human has become the species that has more of this property in the process of evolution in chain of the Life.

The level of consciousness between human and animal differs only in the depth of its manifestation.

As far the level of consciousness differs between person to person, this level differs from animal to animal,

even between those who stand in the same chain of one species, what is influenced by the initial data

and enviroment in the process of creation and growing.

It cannot be said that the dog is higher (more important) than a cat, ant, a dolphin or a cow or Life

or vice versa in any sequence.

Birds sees further, a cat and dog hears more, a pig smells better than human do.

But human has more conscious.

Many have seen how a sleeping dog reacts to what (s)he sees in a dream.

Can an instinctive creature see dreams, or is it still a mind that is at a certain level of the manifestation of consciousness?

A human can easily descend the level of own consciousness by drinking alcohol, but still will remain a human with lower consciousness

and could go down till the level of instincts, which are also laid in human, if drink more.

In other world - human is an animal with more developed level of consciousness.

Animal often depends on humans.

And the exploitation of animals for the purpose of eating is one of the forms of cannibalism - to eat creatures in consciousness.

Animals eats animals, but should we grow with process of evolution?

Which side to keep in this matter is decide only to us, people, animals are in our hands.
