They say that cats and animals don't cry with tears because they are not as emotional as people, but this is crap.
Animals are way more sensitive kind than we are, they feel pain and missing someone, they feel gratitude, and they doncry when they feel that their master is unfair to them, or people in general.
People claim they know everything. Some so called specialists, claim that animals don't feel pain. Or that they have no souls.
That is stupid. They feel pain, they have feelings, and they can love you and if you, as master die, they die after you, because of grieving. That if you as master, were kind and loving, of course. It really hurts seeing this picture of a poor cat with hurt feelings.
