As someone who's never seen or heard of The Animals of Farthingwood, I must say it looks and sounds horrifying.

I watched both Watership Down and The Plague Dogs one weekend at home by myself. Watership Down was unpleasant to say the least, but not as moving as so many people told me it was. The Plague Dogs though...Jesus Christ what a screwed up movie. That scene they mention wasn't even the worst one, in my opinion.
