Question about boxed cats and selling

[Everleigh Aries]

Hi there.

While I am not new to KittyCats themselves, I have never sold them before. I have 42 boxed kitties, some go back to 2012.

I am thinking about attempting to sell some, so I can clean out my Cattery a bit.
My question is, how do I get boxed kitties into SL from my cattery? Do I HAVE to unpack them? I really didn't want live kitties on my cart....just the boxes.

Thank you for your time!

Everleigh
