Most commonly, a "clean" lion contains no inbreeding it their heritage.

Many clean breeders also avoid the "Big Four" in the heritage: Savannah Prince, Boombah, Keyser Soze and Hot Hot Tater Tot

It means, that when you go into a lions heritage, there is nothing at the bottom that says "This lion has X amount of instances of inbreeding" It doesn't have any affect on the actual game, it's just for people who want more of a challenge! Basically, when you go into a lions heritage, if there are a ton of places that say "Unknown" it's clean!

Hope this helps! ^^

Sometimes the first page wont say it has inbreeding, so you have to dig a little further to make sure :)

Clean is no inbreeding anywhere in the hertitage

I am somewhat new, but I am pretty sure they are four lions with very high stats and are very popular for studding. If you go into a lion's heritage, you will most likely find one of those names
