Extinction

[Tad Carlucci]

Define "extinct".

While it may be hard to find a given trait, given the way some people horde boxes, I'd suspect those hard-to-find values are languishing in someone's inventory or Cattery. In addition, I suspect some have non-breeding specimen, somewhere, for all trait values.

I would expect, however, that finding a live, breeding specimen for the oldest retired values would be extremely difficult, if not impossible.

That said, while it's quite possible for trait values to be completely lost to all players, there is probably no way, event for KittyCatS, to accurately answer the question.
