At $2000 (Goal + $500), I'll be writing an epilogue to the novel in the form of letters to and from the main characters Spots and Claws; this will be made available to all backers as an e-book.
At $2500 (Goal + $1000), I'll be getting custom Team Kitty patches made for all backers. I found a place that does them for a reasonable price. :)
So if you're still interested but haven't pledged, or want to pass it around, please do! There will be extra rewards for the next funding goals!
I continue to take notes on this particular experiment. It's been fascinating so far. I don't think I'll be able to say anything really useful until I've run several Kickstarter projects, but I do know enough now to realize that I want to run several more.
