I thought this lawsuit brought against someone whose pet dog was shot has interesting implications. Can you imagine if a similar lawsuit was brought to court in Singapore? It would also have implications for peoples' pets that were trapped in AVA traps. Bear in mind that I doubt it would cancel out a person's right to keep animals off their own property, but that would be a separate right altogether.
For example, say you have a child, and your child runs into your neighbour's garden. Does your neighbour have a right to grab your child and hit them? What this couple is asking for is that an animal be viewed as more akin to a child than to a piece of property.
I have always wondered about baiting the AVA traps. Arguably, one is enticing the cat onto the property - but for the food, the cat might not have walked on.
