I adopted Gus~Gus about a month ago. He was in a store cage so I gave him lots of floor time because of his small cage. I purchased a C&C and he seemed to be sooo much happier. He was popcorning all around and chirping. I purchased him new toys and a castle. Now a week later all he wants to do is hide in his castle (no popcorning or chirping). I still take him out for loads of floor time (Im a stay at home mom and he is my pet). Tonight I noticed that when I put in fresh fruits and veggies, no matter where I place them in his cage he grabs it and takes it back into his castle. Should I be concerned with this?
