Some people, like myself, like to collect and keep lions that your king has fathered. A person may not want their cub and just toss in trades and you may want to by it; but how would you know?
I think it may help people to add an icon ($ with a link to the trade) beside the lions name if they are in the Trade Center when you view your kings bred cubs.

This means you can keep collecting your kings cubs if others don't want them! It could help others gain more currency and help yourself make your pride bigger of your kings blood.

Or maybe there is a special lion you see was born in a different pride with your king as the father and you want it. You don't want to keep checking to see if that lion is ever put up for trade. This way with the $ icon, you can see that one of your kings offspring is up for sale!

Please let me know why you support and why you don't support!

User comments and extended ideas

From Agryo [Side, rolls near-daily] (#84746):
"Though, maybe some users wouldn't want others stalking their cubs bred list in that case; maybe an option to make that convenience private? (So, say, I could look at my king's cubs and see which are for sale, but other users looking at the same list wouldn't see no dollar signs; setting it to be public means anyone can see the $)

"I think that this would help you gain a general understanding of your offspring's worth as well."

From Bridgewater (#22218)
"An idea for notifications for king owners to get a notification of sales to their sired cubs, having an exclamation mark show up on the "View All Cubs Bred" button on the King's homepage or maybe being alerted by a system automated message advising on a potential sale of a cub? If one is afraid of too many notices, then having a means of "Flagging" an interesting aspect(s) of their king that could be potentially passed down and the owner really enjoys to watch out for."
(An on and off switch for the notifications though)
