I noticed that you can't make it sit like the dog. It can be quite bothersome when you want to go mining and the cat follows you to its death. I have seen videos on how to make it "stay" but you have to build and get an egg to put a chicken in a box. They will try to kill it thus they will stay at the box with the chicken in it. I think they should make it lie down or go to sleep.

Sleepy kitty ftw.
But yeah I agree too. The amount of times I wanted to cut that thing open with my diamond sword when I went mining.... O.o
Why not have an option to pick them up, and carry them home so they can sleep there?
I'm joking... it was funny in my head.
