Believe it or not! I just did the same thing! I bought all these flap cats on Ebay. “Stray Cat” editions. I recently bought a beautiful curio cabinet for $800 and when it finally came, the next day it was filled with 9 cats, a female griffin, an amethyst female dragon and about 9 Faerie Glen items.
So far he has said nothing except to say that I needed to insure them. So you are not that alone in this. Glad to know someone else does it too.
