This is the first that I've seen this deck, and it's absolutely beautiful! You've captured the essence and attitude of all the various cats in each card. I love the way the cats interact with each other (something that you really have to have multiple cats in order to appreciate completely!).
I also agree that many of these cards would make a great card or small print in and of themselves, so that would be something else to persue as well.
Here's hoping that you finish your cards successfully (and soon!) and immediately find a publisher for them!
best,
