Both dogs and cats All dogs and cats should be chipped anything else should be put down, we have a hell of a problem with colonies of feral cats here in hull to the point of it making the news not such a problem with dogs though. I had a real problem with cats ****ting in the gravel on my garden until I took pictures of the cat responsible and showed it to the owner who I made come round and collect it all up. I've not seen the cat since. I agree that cats will hunt regardless of how responsible you are but I don't see why I should put up with your "family member" crapping in my garden, lets face it you would no doubt be upset if I came and curled one out in yours.
