Last week, I spent a couple days in Vancouver. I brought Monty with me and left the rest of my furry, feathered, and finned friends at home with a sitter. I came back, and Zeus was behaving positively bizarre. He was clinging to the side of his cage, between his feeder cups, and wouldn't move. When I offered him my hand, he hissed, lunged, and beat his wings! This is something he has NEVER done before. I thought it was maybe the beginnings of cage aggression, or hormones, or both, so I let him be and put him to bed. The next morning, he was in the exact same spot and reacted the exact same way! This time, I somewhat forcefully took him out of his cage and put him on his stand. He seemed to snap out of it for a bit, but after awhile he kept hopping back to his cage to sit at the exact same spot, this time on the outside. I was really quite baffled. He appeared to be in perfectly good health: bright eyes, clean nares, neat feathers, and he was still eating as heartily as ever!
Today, a couple days after this behaviour began, I sat down on the couch and observed him. He appeared to be looking at something, and was mumbling. I came a bit closer, and suddenly it hit me: his feeder cups are metal! He was sitting with his "buddy!" Usually he has the TV or Radio on at all times, and is frequently visited by members of the household. While we were gone, he must have clung to his reflection to keep him company. After removing his cups and covering the outer surfaces with opaque tape, Zeus was immediately back to being Mama's little boy, and was once again more than happy to receive scritches and venture away from his cage.
I'm glad I was able to deduce the cause of the problem, but I do have a question: would it be beneficial to get him a companion (of the same sex), or should I leave that alone?
