This phenomenon has nothing to do with the cats. This is because out of the viewer and i discovered this on my cats already in November. I then wrote to the Firestorms support and they argue that the fault lies in the SL viewer v3 as the new Firestorm is based on.
Here is the entire thread about my problem and I hope they fix it for the next update.
