I hate my cat, how can I get rid of it?

The cat on my ship annoys me, as it keeps following me and, when it does, it parks itself in front of what I want to interact with, thus preventing me from doing so unless I move the mouse away from it.

Something like this is a pain with the shiplocker, because here it sits and covers most of the shiplocker and there's only a tiny bit I can check before my mouse is off it. More annoyingly, it sometimes parks itself at the flight control and I can't even access it.
