If you want instant gratification when renovating a house, then nothing can beat the erection of a fence. The Australians (Hi Linda!) obviously think so, as they went so far as to erect the State Barrier Fence of Western Australia, formerly known as the Rabbit Proof Fence, the State Vermin Fence and the Emu Fence. A pest-exclusion fence, it stretched 2,023 miles when it was completed in 1907. (Who needs Wikipedia? Me, obviously, but not you, you can just read this drivel!)
Within three days, we appear to have transformed the garden. And, oddly enough, stretching a line across appears to have made it much bigger. I look forward to partitioning some more and gaining further acres!
Ours is not to keep the rabbits out but to keep the dog in, a pest-inclusion fence. It was a project that I always had in mind, although my thoughts were in the direction of a hedge rather than a fence. Then the dog arrived and a hedge would have taken too long to grow to provide the required barrier.
The dog is eyeing it up as an interesting challenge. It is five feet tall because he can jump up to my nose from a standing start. There are no gaps for him to squeeze through: he can casually slip round the side of the front gate without a second thought. His only exit route, as far as I can see, is the wrought iron gate at the other side of the house. He'd have to dig his way under. But then he's a terrier and that's what they do. Somehow, I don't think that we have yet created a barrier that will confine a determined Sprocket after a cat!
