That depends on if you want to sell the cubs or to keep it/just so it doesn't show inbreeding on Heritage page.
Heritage page only shows inbreeding among visible lions - so, 5 generations back, 6th generation from a lion wont add to inbreeding number anymore. If you're ok with that, you can consider a lion clean for yourself.

However most people consider inbreeding in all heritage, and check further to see if the lion is inbred further than visible heritage page. They'd still consider a lion dirty, even if it doesn't show inbreeding. So pretty much, once inbred, always inbred, there's no way to "re-introduce" a lion into the bloodline if it was ever inbred - it will always carry that info in its heritage, and anyone who check further than first page can see its dirty.

There's no such thing as "first page clean" or whatever some people are trying to introduce. Heritage is another word for genealogical tree, so you cannot ignore the fact ancestors were dirty.

Dirty means inbreeding and big4:
Keyser Soze
HOT HOT TATER TOT
Boombah
The Savannah Prince

Clean, for your own pride, is whatever you want it to be. If you just want to see no inbreeding on the first page, Mad Hyena is absolutely right. Just wait a few generations, until the same lions get pushes to the second page.

If you're trying to sell "clean" lions to people, they are very picky and it's easier to ask them all individually what they want from a clean lion. A bunch of us don't care if a lion is related to Keyser...

And although a lot of people will insist it, neither Keyser Soze nor The Savannah Prince are actually inbred, or "dirty". Soze has no parents in his heritage, TSP has only mothers... The reason people avoid them isn't their heritage, it's just that they're related to so many site lions that it's hard not to inbreed if a lion is related to one.

how can you tell if a lion is actually bread from one of the 'big four' and not just a duplicate name? does anyone know who the 'big four's' parents are?
