Given that the article you are commenting on has nothing to do with aggression, it is not as apparent as you may think that you were asking about "dog aggression towards cats" instead of "aggression of cats."

Thank you. Sadly, these bans have done more harm than good. It doesn't fix anything, but using a wide collar (2 in or 5 cm) should at least prevent injuries.

We only train dogs. But there are cat trainers. I would google for it.
