Well, aeclectic.net has pretty much just about every deck I've ever come across and many that I will probably never lay eyes on in person, but it doesn't list a black cat tarot deck. You're positive that that is the name? Could it have been an unpublished deck by an artist, or something like that?
And if you are just looking for a deck with explanations, I could suggest the Quick and Easy tarot deck... It has the explanations for the card and its reversal on each card, if that's what you want. I personally think it's more fun to learn how you would explain them yourself
I wish I could be more of a help... good luck!
