My cats go outdoors - but sometimes if you’re going out they’ll just follow you. Very annoying when you have to catch a train and then they start following you. But occasionally we walk them down to a mini woods a few minutes walk away and that’s great. People are very interested in the concept of taking cats on a walk. No harnesses, they just follow us
I have one because we have too much shade to grow grass. We have a 3 storey 60s house and a small, north facing garden. That said only one brand was recyclable at the end of its life, which is a shame
