This exactly! Cats don’t need to go for walks or be let out at regular intervals. You can even leave them home without a sitter for a week or so if you have automatic litter box and feed set up. (I have cameras and a neighbor who is available for emergencies). Cats are so low maintenance, but also I don’t do well with dogs smothering tendencies.
I was there last November, I rode the train from Schiphol airport to Utrecht. It is a very nice city 100% would go again.
