Why was the price of cat ears increased

[Angel]

I didn't see any changelog mentioning a price change, and a similar item that can also hide headsets, headbands, still costs only 60 credits, but cat ears went from 150 credits to 300 credits. I wonder, what was the reasoning for the price change, and if there's any chance for it to be reverted?
Costing 150 meant you could buy it roundstart as a staff assistant, if the issue is the ability to hide headsets being too strong, then headbands price would also need a price increase, and even then, I don't see it as that big of a problem when you can just hide headsets in your pocket for the same effect.
