The great thing about encouragement and the words from our Greys is you know they are genuine. I don't think Greys know, or for that matter care to know, how to fake it like so many humans.
We have three pak-o-birds. I ordered two small size for our Caique and our Jardine and went ahead with the medium 'African Grey' version for GreycieMae. It is huge and cumbersome to take anywhere. I've taken to throwing Greycie into one of the smalls for short rides and she's a big 'ol heifer at nearly 490 grams. She fits in the small just fine.
The one thing I don't like about the pak-o-birds is they can still destroy them no matter what Celltei will tell you. Even with the stainless mesh upgrade, GreycieMae figure out how to chew a hole in it. She literally destroyed the inside of hers in just a few short stays in it. So she's back to sitting in a metal cage while the other two get the pak-o-birds. If HRH Inara isn't a big chewer she'll be fine in one. I'd still suggest the stainless mesh upgrade though.
