I'm sure there were other Who's Cats before this one. I could have sworn there were some backed up in Dropbox.
Still, this one is pretty current. I don't know a thing about Pokemon (my son is more of a Yu-Gi-Oh player) and I've not been involved in any Pokemon Go hunting parties, but anything that gets outside and interacting with people can't be all that bad.
Sorry the strip is up late today, but my internet connection decided to take a hissy fit this morning and it turns out I hadn't installed Dropbox on this PC. Not a fun combination.
