I want to sell my cats....

[Dahlia Silverfall]

I want to sell my cats but I cannot set to "BUY" even though they're supposedly transferable (I can see the checkmark.) They are SL14B carnivalesque kitties. Why can I not set them for sale? I looked all thru the forum for this (by several keywords) and didn't find anything to tell me EXACTLY how to set for sale. Please? Can anyone advise me as to what is wrong? Thanks in advance....
