No, but heard a story or two when people tried actually shipping parrots this way! lol Could you imagine a chinchilla on the loose at the post office! Was bad enough when they called cause of a leak in one of my boxes, which ended up being chinchilla dust. I had to assure them it wasn't going to explode!
Aww!! 7 and 8 look just like my sweet little Poe I lost last year to pnuemonia - I was so thrilled when he came out with those cute eye patches - he was named after kung fu panda Po.
