Hello Hannah
Which special breed are you refering too?
Do you perhaps mean the special birth kitty the Dreams of Eire the random birth for Sint Patricks day?
If so, I have seen them on the secondary markets for sale.
I think a notice with landmarks to all private sellers and secondary markets are still in the past group notices of the addicts group.
Kitten Longmeadow is sending that out once a month I believe but perhaps once per two weeks now not sure.
Anyway what ever you may look for the chances are high you find it on those markets.
Also if you specifically know what you are looking for it might be worth a try to post your request in the wanted section of this forum.
I hope this helps
