First of all, i love your maine coon.
As for the camera part, what do you mean clicking sound? This one is by far the most worrysome.
DZHEXKeep an eye on it. If it clicks again stop using the camera, altho i feel that next time it will probably be dead instead.
The view occasionally froze, then there was a quiet click and it started moving again... Absolutely no idea what it was. I tried to turn the camera around to see if something moves when it clicked, but I didn't see anything. Now it's not happening anymore.
