Death and Candy
I am going to sit here and pout angrily until ferret skins are available in Skin Tyte!
I think there should be more non-mammalian skins too. Lizards, frogs, birds, fish etc.
Lizards and birds are kind of available.
You can piece them together through various multi-pose items. The common schtick with those is they have most in a multi-pose form because you are more likely to buy more than one to make the animal you want, which means more $$$ for Gaia. You can find items that have wings that replace the arms and there are some long tails out there- there are just not full skins available to cover the base.
I am assuming that the multi-pose item is going to be the cornerstone of what animal items are going to be comprised of. This is what I assume because it just makes sense considering it's the way they handle humanoid items.
