So, funny story: I wake up, take Rudy out of his cage, play with him for awhile, and put him back in his cage so that I can leave and go to Starbucks. So far so good. Here's the funny part: three hours later, when I return and open the door, I hear Rudy screaming at me like usual. Only he is not screaming from the right, where his cage is located. No, he is screaming from the left, where my bedroom is located.
That's right - he had escaped! It seems the little goof ball had pushed out his food door, flown around looking for me, and when he couldn't find me, decided to spend the day in my bedroom on my chair looking out the window. He was so pleasantly happy to see me, I simply couldn't be angry. But I have learned my lesson: secure the food door!
Rudy is indeed a handful. I recently took several videos of his refusing to go to bed at night. That will be up soon.
