I've been busily collecting pictures and making tokens in order to play with Roll20. So far, I've been dividing them into three categories: Player characters, friends of kitty, obstacles to kitties. Here is a quick sample of some the ones I'm making available to the players.
All of these came from a quick Google image source, and were made into tokens with Token Maker.
I was going for cute and cuddly with the intent to keep adults and children engaged.
