Haha, I will be sure to tell him
Well, Mork shakes the bars of his cage so loudly that I can hear it in my bedroom (opposite end of the apartment), which scares Rodya, Sonya, and Pico, and they're not even near him.
Also, if I clap or snap my fingers when he's doing something I don't want him to, I get no response. At all. It's kinda like clapping at a wall, actually. Lol!
Also, I've held him about a foot away and talked softly, then louder and louder, only to get no response. If I do that to Rodya, Sonya, or Pico, they look at me. Mork will just keep checking things out in the room.
If there is a startling noise, everyone else reacts -except- Mork.
Lastly, when I go to say hello to him, he doesn't wake up, unlike the rest of my chins. They hear me coming and hop up, wake up, or at least open one eye to tell me to leave them alone, haha. Mork only wakes up if I accidentally bump his cage or something jolts him.
