Would I be wrong to assume that you live in North America, Greg? It's evidently a different culture here in this respect/

Cats roaming free from garden to garden really is the normal way in the British Isles, and I believe in other parts of Europe, and always has been. If someone doesn't want a cat in their garden, it's up to them to make it catproof, rather than for a cat owner to stop their cat roaming. Quite a different situation from that which pertains for dogs.
