Oh wow you are spot on. He is just on the tail end of a rather fruitful molt (so many feathers this week!). I hadn’t considered that at all but that definitely makes sense.
We are conscious of the cats but they’re really interested in him anymore. He’s on the top of a tall dresser and we bought a scat-mat to train them when we first got him. The batteries have been dead for months but the cats still won’t go near the mat haha.
If anything he gets as excited as they do when we shake the treat bag to coax them out of the room cause he knows that sound means it’s flying time!
I’ll be sure to keep an eye out in case anything else seems off in terms of his health though as well. Thanks for your advice!
