I just bought this deck on a complete whim... I was about to get the Ludy Lescot deck, since I'd been considering it for so long, but instead I walked out with this weird collection of felines that I've never even noticed before? I was a bit disappointed by the art once I opened the pack - much of it seems naive and some of the cards are poorly drawn, like the artist does not have a complete grasp of how digital art works (is supposed to work). SO MUCH COPY-PASTE, ugh... and so little blending of elements together... Still, I do appreciate that most of it is drawn (even if items are only drawn once and then copy-pasted); and not photo-manipped.
Also, I do like the colors in many of the cards, and according to an acquaintance my deck's first ever reading was pretty spot on. So... I'd say it's an okay deck. Bonus points if you're really into cats, of course.
As for the World card... I honestly have no idea how some people can view this as a racial problem. This is an entire deck celebrating black cats as amazing portals between worlds and animals with high spiritual power, with the Fool (the one lacking experience and wisdom) being the only white one. I highly doubt anyone was trying to moralize on "white is better than black" when they thought out those two cards. I'm a newbie, but the second I opened the deck and looked at the cards, I thought "oh okay, so now that the journey is complete, the character becomes the Fool once again, for a new journey. Cool." If anything, the WHITE cat is the one who's inferior to the black ones, because she's the only one who's a blank slate. But again, this is about symbolism, not race.
