Is there a cure for animals to see more than just certain colors?
Yes, mice are color blind. Humans have three color cells in there eyes, but since mice only have two, they see a limited amount of colors. They don't actually see in just black and white, they can see certain colors, but not as many. Animals such as dogs can only see in black and white, while other animals such as cats can see some color, but not all.
So they will live in they envoirment . Animals, excluding humans, (which are animals by the way), don't just live where they want to, they require a certain habitat that will sustain them. ( certain types of vegetation, water, creeks, rivers) Available food source and breeding requirements play a major role.
