I work at London Zoo there is very good, we take care of different animals, members of our zoo to protect animals. We have not only the zoo but also of veterinary clinic. In different countries, we find sick animals we pick them up, they are living with us at the zoo when we realize that they are healthy, we are releasing them well, unless of course they want it. Our zoo is not enough money and therefore we want you to ask you that you have invested some money in our zoo. And when you come and bring food to staff members.
