There is money in cats, not so much the other animals. Think about what people spend on toys, beds, food, catteries, etc., ferret owners (typically) will not spend the same kind of money, there isn't an industry built around it. Kinda like trying to get rid of trout...
I have 5 cats and 2 dogs, all our cats are desexed, fully vaccinated, wear collars with bells and my details and are kept in at night. I would consider this to be responsible, and I fully expect other cat owners to do this as a minimum. I don't find it acceptable for my own cats or any others to poop in my vege garden and have turned the hose on my own and my neighbours cats on several occasions.
I found at one stage one of my cats was harassing a neighbours cat on their property, so I, the responsible cat owner, took steps to contain this cat further. I did not expect the neighbour to take steps to keep my cat off their property, as some of you seem to think is appropriate.
If a neighbour is causing too much noise, we expect them to make less, we do not simply block our ears.
