White lions, also known as blond lions, are not albino, but are leucistic and are uncommon in the wild as they lack normal camouflage. Common mutations in big cats are albinism (pure white), chinchilla (white with pale markings), leucism (partial albinism/cream) and melanism (black). Mutants are natural variations that occur due to spontaneous genetic changes or the expression of recessive (hidden) genes through inbreeding. Here's a nice write up White Lions I found So far all I have been seeing is that they are the same as tawny and oddly enough they have extreme difficulty surviving in the wild thus far. Like everything else, it seems to come down to genetics. Which is why I think you have some very large white tigers and other not so large ones. I have now read this multiple times that White tigers have been inbred and bred with other sub species to create larger or showier cats, larger ones being inbred with Siberians. I found more in books, but can't get to them at the moment. In the tiger extinction thread, I posted a scan of a letter from the JBNHS about two white tigresses shot in India. The book only covered the first two years of his life, but in this period he did well. I never found anything else on white lions. To the surprise of many, the white male cub was immediately accepted by his peers. I had a book on Timbavati lions, but had to let it go when I got an offer I couldn't refuse. The number of Frankensteins far exceeds the number of moviestars. I saw many white lions and tigers with too many problems to describe in far away places. I could continue for some time, but the bottom line is captive white lions and tigers often are large animals. Breeding white lions or tigers, however, is a risky business. (603 pounds). Both cats were in excellent condition and I saw both from a few feet only. The white male tiger was 249 kg., whereas the white male lion was 273 kg. All big cats they had were weighed every week and I saw both the scales and the charts. Sankhala, Mazak and a host of others concluded white lions and tigers usually were a bit larger than others. The trainers I interviewed agreed. What I saw in facilities confirmed the observations of others. I visited one which had a white male tiger and a white male lion.
