Animals and disorders

 Are animals running in the wild in some psychosis ? Do they have reality ? Do they know what there is and what not ? Do they have traumas ? Do they hear voices ? At least they kill some more amazing animals like some humans in disorder. Some study found that mice would have schizophrenia like condition. Maybe any animals are known to humans as quite insane at least. But some animals seem very peaceful and sane. Many animals are not evil. Are cats psychopaths ? Do they not remember just as immatured that there is other being than them selfs ?  Do animals grow matured also ? Are they then well ?
