When we visited the National Zoo and Aquarium in Canberra a couple of weeks ago, we discovered they have a Tigon - a cross between a Tiger and a Lion. These animals never interbreed in the wild, so such crossbreeds are usually as a result of artificial insemination in a zoo or such. They are also usually infertile and have other genetic problems - which would indicate to me that this kind of thing isn't a good idea. Does anyone know how old the Tigon at the National Zoo is and where it came from ? Personally, it does make me quite angry that people feel compelled to experiment like this - just because you CAN do it, doesn't mean you SHOULD. There is no valid reason I can think of in the name of animal conservation to create such a creature.
