Thanks everyone!
There is natural light (cage is in the living room). I think he is so used to me getting home around 8am and saying hello that he just waits for me to get home bc he knows it's playtime. He usually is anxiously awaiting my arrival home from work (I am a human toy for him with all my badges and stethoscopes and pockets on my uniform shirts and pants), so he loves playtime after work lol.
And when I put food in the cage (usually around 7pm) he will come out, eat a bit, and go right back to his pouch. Sometimes he will want to come out but it's just to snuggle, not to play.
But I'll be off midnights soon and be able to get him and our new baby girl (WHO WE PICK UP TOMORROW!!!) on a good schedule.
Thanks again everyone :)
