if you look on US cat forums (I was searching for advice on a cat issue I had at the time) they are very down on cats being allowed out – they regard it as being cruel and dangerous for the cat, and seem to spend loads building runs and stuff for them
Tis true. They are convinced that any cat let outside will be instantly flattened. My wife wanted to keep an indoor cat but I would not have it. We live in a cul-de-sac which backs onto another cul-de-sac which in turn is near a dual carriageway – about 1/4 mile away. It's within cats territories in theory but there are loads of other cats there too, and a great big area of woodland full of bunnies on THIS side of the road. So I thought he'd be safe. My wife was terrified for him, and even suggested getting him de-clawed which made me sick to my stomach.
He's been fine for three years now, and seeing him really loving his life as an outside cat has mellowed my wife a lot. Cats in the US (in my experience) are often wretched messed up little things, which I suspect could be due to their incarceration.
On the subject of feline road safety though, I do have a theory. I saw loads and loads of dead cats by the roadside when cycling in the US, and I don't think I've ever seen one here. So I wonder if the cat population being predominantly outside here over the years has led to natural selection of road-safe cats?
