We're considering getting a cat. Our garden is probably part of neighbouring cats' territories - we see two different cats crossing it on different routes and never at the same time, but none actually stay in it for long. Whenever there's a new cat in the immediate neighbourhood we hear caterwauling and fighting in our garden until they establish their new hierarchy. We also have several months of spreading Silent Roar to prevent them soiling in the borders.
If we get a cat (or possibly a pair of cats) how can we help them establish their turf? And how can we prevent them from soiling in our borders without compromising their 'ownership' of our garden?
