It should also be noted that he became less prejudiced in his later years

Not defending or anything, just that back in those times it was borderline a requirement to be, for modern standards, "racist".

That said, fuck his cat naming sense. In this regard he's really the opposite of Junji Ito, whose one of the few nice/comedic works of his I know of is about his experiences with his own cat.

While Lovecraft's own histories about his cat/self-cat inserts were deemed too much even for that time.
