''Note: Status does unknown things to tamed [[animals]], if you have any information, please edit this''
Edit: The taming status can be used to know when your animal will go untame. Here is an explanation on how taming seems to work. When you tame an animal numerous times, at a 42 taming skill, for example, your animal will have a max "tamed level" of [42]. Over time, this value will [[decay]], and examining the animal to check its status can tell you on average how high this "level" is, with "upset" being the least reliable status, as your animal could go untame without further warning.
