What should I do if my neighbor who has a large number of cats interferes with your life

I didn't expect that this kind of pet disturbing people on the Internet happened next to me today. My neighbor was an unreasonable villain. He raised more than a dozen cats at home and did cat breeding business. He did not pay attention to environmental sanitation, which made the public corridor smell bad, and caused trouble to others every time he entered and exited. When arguing with the other party, the other party not only ignores it, but also wants to hit someone. I had to call the police to deal with it. After being handled by the police, I restrained myself for a few days, and then repeated the same trick.

Please give me an idea, how should I protect my rights? Which department should I ask first? I'll see if this problem can be solved through legal means. If every time such a thing happens, it will be solved through media exposure, then the cost is too high. I want to resolve it within my own ability by checking the law by myself, without hiring a lawyer, department complaints, and court prosecution.
