Our Marble passed away this afternoon quite suddenly. Hanging out in his cage and I went to open the cage and let him out but found his ladder and perch dislodged and he was taking his last breaths on the floor of the cage. He was just fine beforehand, eating, drinking, playing. Had flown up on my head for the first time maybe 2 hrs before that. We had only had him 12 days, from Petsmart. The only thing different today was my husband and kids were playing w the guitar and amp for a bit. It was a but louder than the TV usually is but not excessive. Could it have affected him? At first I was thinking a seizure perhaps, because of the items in the cage being dislodged. I know for sure no one had messed with him. :/
