Are cats allowed free reign in the UK? The owner has no responsibility for their trespass?

Thinking that the owner fined for the problems associated with their pet may cure this problem faster then new air gun laws.

I can instantly smell when a male cat had urinated in my wife's garden. It's pungent and disgusting. As well as the direct burial of the droppings in her garden.

I've little patience for them, and we are on a farm. No neighbors for quite a distance. Fortunately they are easily captured in a live cage trap and " relocated"

The newly hatched quail pheasant and turkeys appreciate this I'm sure, although they are also clueless about the big picture.
