This is just a thought but I was thinking, sense you have to wait for cubs that are under 5 months to sell or trade them, you could still do that when their that young but you would have to have a lioness that has her own cubs that could almost be a foster mom. I’m not really sure how it would work, but it would be something like your trying to buy a 3 month old cub from someone else and you would have to wait 2 days just be able to get it. Instead, you could buy it and IF you have a lioness her own cubs, also under 5 months, then you can put the cub you’re trying to buy into her litter. I don’t know I just thought about it like an hour ago.
