This may already be an existing thread, however I was wondering which zoo animals are the most money-making in zoos. For example pandas may attract more visitors, however the cost of having pandas (not to mention the added government loan costs) most likely means pandas are not money-making. Similarly, animals such as duikers are unlikely to attract visitors and therefore will not create much profit. I was thinking animals such as lemurs and meerkats attract visitors whilst not being too expensive to keep. Perhaps this applies to bears and big cats as well?
