Eurogroup for Animals’ folder Think Positive, contains all the arguments in favour of a Positive List as the most preferred policy instrument to regulate the trade and keeping of exotic animals as pets. Not all animals are suitable pets. There are animals with such specific needs, which are compromised when kept as pets in captivity, with dire consequences for animal welfare and animal health. Some animals are too dangerous and can inflict injuries to humans or other animals. Other animals are escape-masters and can pose a danger to the local ecosystems and biodiversity if they escape or are released into nature. Still other animals can transmit diseases to humans (zoonoses) and thus pose a threat to public health. The Positive list is an indispensable instrument in countries with a booming exotic pet trade. But also, in countries where not many exotic animals are kept as pets (yet), the Positive List is still an important instrument to prevent the risks associated with the exotic pet trade from arising in the future.
