The bug!

I downloaded an addon from mcpedl.com called the Demogorgon.  ( http://mcpedl.com/demogorgon-addon/ ) I played about 10 minutes and when I found one that natural spawned it killed me. The death message said: Player was slain by cat. After I went to an other world and installed the addon. I went to a village and summoned a demogorgon. When the demogorgon shouted, all the cats attacked each other or the villagers and also can kill the player.

After I downloaded an other addon from mcpedl.com called the Crash Team Reaching. ( http://mcpedl.com/crash-team-racing-addon/ ) In this addon the vehicles have an openable inventory and on the top left it says cat.
