Due to concerns over inbreeding, most zoos have stopped breeding these feline color variants. The purpose of this thread is not to discuss the ethics of the movement because that has already been discussed on many different threads on this site, and a general consensus seems to already have been reached. Instead, the purpose of this thread is to attempt to create a database listing the current populations of all white tigers and white lions in captivity worldwide, and then to maintain this list as they get phased out over time. As far as I can tell, no such database currently exists. Attempting to find information thus far has proved to be difficult, with most sources being either too vague or too outdated to be taken seriously. Lucky for me though, I have this site full of people worldwide who I hope could help me out. With all that said, can you all please list the zoos, aquariums, wildlife parks, casinos, etc. that you know for sure currently exhibit either white tigers or white lions, as well as how many of each they hold (including those that aren't on display)? Those two bits of information are the most important of what I’m looking for, but any additional information such as age or sex would also be appreciated. Thanks in advance everyone!
