About 2 weeks ago I tamed a cat and 2 birds, I decided to go back to my Minecraft home and continue to build whatever I was building. I got hungry (in real life) and turned my tablet off to go eat dinner, when I came back my pets were gone as if they vanished. I let it slide that one time and a few days ago I went to go find birds to tame, I found 2 and went back to my Minecraft home. But when I exited out of Minecraft and came back they were gone once again. I tried shutting down my iPad but nothing happened. So today once again I go looking for pets and I found another 2 birds that I tamed and went back to my Minecraft home but like an hour later I decide to go eat dinner and come back with them gone. Note that I know I tamed my pets because they followed me home and teleported when I went too far. In total 6 birds and 1 cat have disappeared out of nowhere. So now I am reporting this because I think it might be a bug.
