I have a bounty of items available for the trade of a cat tail of any sort, as well as plenty of CE (But I prefer to trade because I have so many nice accessories just stockpiling up.) Please note, any of these accessories are available for trade despite their rarity. I just really want a cat tail (even if it doesn't match my outfit's color scheme.) Some of them are not possible to get outside of trading, so choose wisely. and as always, happy hunting.
