This is an entertaining little shop that I visited on a past trip to Stockholm. As one might guess from the name, it's dedicated to all things cat. Things for your cat, things with cats on them. Clothing, artwork, calendars, trinkets, etc. On my last visit, I got a Swedish calendar featuring firefighters with cats. Make that hunky firefighters with cute cats. Didn't matter that I couldn't read a word it said. :)
On this visit, I didn't find anything I wanted to buy, but I'll still visit again if I ever make it back to town.
