So pretty much overnight my sweet cuddly friendly parrotlet turned into a monster! He is very serious about guarding the top of his cage today (which he has never done before) and LATCHING on to everybody, harder than he has ever bitten before. He even attacks his toys and rattles his dishes and throws his food and screams a LOT. Earlier today I even saw him rubbing himself against his toys. I have not changed his food, or his daylight/night hours, and he gets plenty of hours outside his cage and has plenty of toys. Nothing else has changed! He is still very active. Is this hormones?? How long will this last! His personality has just completely did a 180 overnight!
