So long story short, I have the celltei airline approved bird carrier and Im trying to get my green cheek used to it. I am moving in the next few months (hopefully) and in the process he will have to sleep in this carrier for a couple of days. I was wondering if anyone know if its safe for him to sleep in the carrier with the flaps lowered? Im very nervous he wont have enough ventilation.
