I periodically visit Yuko's folks with Yuko, and when I do it is not unusual to stumble upon the cats exploring. Mika is the trailblazer - she's fearless and investigates things with great vigor. Gonta, on the other hand, explores primarily to discover new hiding places. As you can tell from the comic above, some hiding places are better than others. I'm just relieved Gonta isn't a cat out in the wild; something just tells me Gonta couldn't hack it.
Speaking of cats, there are a number of new things in the Johnny Wander store available for purchase, including this handsome print of a girl with her eight cats (click the image below to go to the store):
There are also cat bookmarks that I think you will enjoy! Take a look!
