they are mighty cute, but white lions can't be integrated back into the wild as aren't a natural phenomenon. In South Africa they are bred largely for canned hunting. When I was working out there in wild animal welfare, the going rate for some sicko - European or American generally - to shoot a white lion was exposed as about R200 000 at least (£13 000 roughly). At least the German lions are in a park.....have you ever seen an old white lion though? Do wonder what exactly happens to them when they are no longer cute.
Sorry, but have seen the dark side on this issue and it's something I feel very strongly about.
