I also put him in the big cage today because he has been trying to fly in the little one, and he was getting around really well but also seemed like he hated being stuck in there. He likes the big one a lot, it took him about an hour or two to get adjusted but now I see him flying around and playing with his toys- he also doesn’t freak out when I put him in there now like he was with the little cage (he does still fly out as soon as the cage is open )
