Yoshi's cage is in the main room of the house-he has "permission" to come and go as he pleases...Sometimes he gets bored...and seeks me out-startled me a bit the first time..I was getting ready to leave and he came and found me in the bathroom where I was putting on my makeup-I looked down and was like "oh! Hi!" and he sat on the top of the toilet and watched me and whistled at me until I had to go. We have a constant "conversation" of whistling back and forth if I am not in the room with him, I think he likes to be reassured I am around. He's only 6 months old so as far as vocalizations go it's the "wolf whistle" the "dog call" and the "hey you"...and parts and variations of all of those...and a loud "beep" which I'm not sure where that came from...lol
So as far as time spent together, it's pretty much all of the time...
