Indeed, our grey has a perch she regularly shits on, then climbs back down and away and back to the playground. We collect her efforts, which then are nicely deposited in the garden compost, where they create a rather fat and moist soil condition for later parts of the garden. She is a talker. We call to her to come play and she'll often respond with a solid "Tuk!" if she's not interested, and we should hush, or a "clirp!" if she's not interested, but wants to talk about something else, or a "<favourite imitation of some befuddling device>" if she's actually on her way and just coming around the doorway for a bit of fuss and fun on the floor .. But! You should never have a grey unless you are prepared to spend a lot of time with it. Anything less than regularly, daily interaction, is going to result in a kind of neurosis the finely tuned attenuators of the human mind may not be readily prepared to endure. Be aware, greys can be Craa-AA-zy! ..
