In the past 15 minutes I received the message "Cat went up in flames" twice in my current village. After the first message, I removed an open campfire in case a cat wandered into it. But shortly thereafter I got the message again. There is no lava in the village, just a lot of torches placed to light up the area.
Does anyone have any idea what could be happening? I can't tell if any of my tamed cats are missing because I never counted them, but I just bred a couple in case the cat population is generally in danger.
Thanks, I got the "Cat went up in flames"! message again shortly after posting my first message in this thread. In the meantime I have made all my tamed cats sit down and hope that the cat massacre will end. I also completely blocked access to an out-of-the-way one-block-wide waterfall that led to an abandoned mineshaft under the village in case cats somehow fell in, but I think it highly unlikely that this was the source of the danger. You have to wade through a lake to get to it.
