Thank you for ruining my childhood... O_O
****** does not apply to animals.
Yes it does. For several large mammalian species, it's a detriment genetically. Inçest is only wrong because it's genetically detrimental to our species's survival (think of an error checking machine and the way torrents work).
I do not think animals are at an intelligence level where ****** applies as an immoral act. Yes the gene pool will get weaker. That is a given.
Didn't they tell or state the obvious in the movie?
Well I'm a lion so, it doesn't bother me.
Animals do interbreed. mx:))
