hi, and welcome to KittyCatS! - "retired" means, that those traits are no longer available to buy in our starter packs or special collection cats. it means they are not in the "genetic pool" any longer from US.
they can be found in secondary markets and preserved through breeding, so they are not "gone", just simply not something we will include anymore as possible traits in the cats WE sell.
they are not unwanted, or devalued, in fact it just can be the opposite, since it's up to the community to preserve those traits
again welcome to KittyCatS! and i hope that helps!
