Again i hope this helps clarify, "retired' ONLY applies to normal traits which were available in our starters OR our Limited Edition Collections.
Our "collections" or "special cats" have always been limited Editions whether they carry passable traits, i.e., The Gerbera Eyes or not.
So, if a collection does contain a special trait, as with the Lazy Dayzies having the "gerbera eyes" this is NOT anything we consider to call retired as it was never in a starter, so, there is no need to "retire" it.
Our collection cats, are the same as a starter (with a costume) unless we specify otherwise that their traits can pass. If that is the case, we let you know AND those are only available for purchase from us during the time period the Collection is sold.
I really hope that helps clarify. On our "collections" page you can see which feature we put into each Collection as each time we do them a little differently.
Thanks and again I hope this helps clarify.
