Since I haven't been active at all lately, I am still missing quite a lot of those little beauties.

For Cat's Eyes I can trade

Mutagens,
Energy Drinks,
Rainbow Jars,
Major Scrolls of Insight,
Magic Foods,
Pink Fish Eggs,
Gray Jars,
Amnesia Potions,
Magic Bombs,
1 Change Sex scroll, 

Tactician, Trainer and Druid Invites

All regular Blueprints and Schemes (not the ones you get from the Battlefield)

Vermillion

Building Materials

I MIGHT even be willing to trade my last remaining
Unicorn Festive Outfit 
but bear in mind that I will not part easily with that one, fair warning ;) (if you don't know what that is, check in my Stable group "Spring Time Revelers", -the Outfit works basically like a Rainbow Jar just that it gives your Unicorn this special appearance and permanently adds +5 Energy to the pet)

I can't give you cat eyes because I can't get them any more but I will give a female defender thodama for that unicorn outfit!
