Mostly good
I was waiting for the butter to show up in this. I thought maybe the butter was supposed to be the cat himself or the uvula of the man. The music made throughout this also made it very creepy. What was probably the best part was the animation. Everything was just so amazingly demented looking. Every second, the lines these characters were made of just seemed to be plopping all over the place, not that that's bad.
I imagine a sick demented guy would do that to his cat. It looks like the old man is just melting with all that saliva coming out of his mouth. All in all, this was a good cartoon because it was quite unpredictable and downright creepy, if that was the aim. I never heard of a crazy cat man before. The paper background was great too.
