Human psychology has not changed: people still like to interact with pets and be surrounded by beauty. The only thing that is is in question is the form and comfort of these fast-changing conditions.
Scientists propose genetically modified organisms as pets: small copies of large animals, hypoallergenic cats and designer aquarium fish - luminescent or with colours and patterns that can be chosen.
For those who, for various reasons, cannot take care of or interact with real animals, but desire such a thing, scientists can offer interactive robotic pets. They help to maintain a zeal for life and the emotional well-being of elderly or sick people, hospitalised children ,and many others.
