The cat or dog (tamed) sits when exiting the game and cannot be controlled to stand up after reloading.Even with water, they won't follow you, dogs won't help you attack, cats won't give you gifts, and feeding won't help (and can't be retamed).When you attack a dog, they fight back (but their eyes don't turn red).

They seem tamed in some ways: cats don't leave when players get close, and they all have collars.

But in more ways it's more like the wild: it'll fight back, it won't follow me

I've tried reloading chunks (a few hundred blocks away from them and back again),but it doesn't work.

And you can't tame them again.

(My English is pretty bad.)
