This is Jonathan Harker Cat. Contrary to what one would expect of his namesake, he is very obviously an agent of the Dark. Note the resemblence to a milgwn, not to mention the fact that he enjoys laying under Kleenex in an obvious attempt to force all the Old Ones to live with runny noses.
When Jonathan Harker gets angry, he attempts to intimidate the population of the rest of the house into submission. Here he is trying to starve us into letting him sit on my laptop by denying us access to our dinner.
