Unfortunately, thanks to a
neighbour's cat, they don't get past being 6 rows of bricks in
length.....


Politely ask the neighbour to keep their cat off your land, under the new
companion animals act they are obliged to do so. If they are not
cooperative your local council is the controlling authority. In the words
of Dr John Wamsley "If you want to keep small mammals, birds and reptiles
from becoming extinct then hat your cat".
