Alcoholic neighbors

New here. Ive had an ongoing issue with my neighbor thats reached a tipping point. It is a mid forties married couple that has a clear drug and alcohol problem. Ive ignored it for the most part (drunk fights in the middle of the night, wrecking into his own house, crying spells and knocking on other people's doors at 1 am) but two years, one of them lost their job and he's been on a two year bender ever since. They recently got upset with me about running my leaf blower and getting leaves in their yard. I tried to apologize and it turned into a me getting yelled at (while they were both drunk). They have a cat the has crapped in my yard for 3 years straight and I wish it was an option to simply ask them to put a litter box in their house for the cat to shit, but I know that it wont go over well. My main concern is I have two kids under 3 years old and my other neighbor is 4 kids all under 6 years old. The non stop drunk driving is a concern for everyone and we are all fed up. They wont get a job, stop drinking, and can't be reasoned with. The husband has walked over, unsolicited, to the neighbors house many times while the kids are playing in the front yard and picked one of the kids up to hug him without the parents consent (while drunk of course). The drunk driving and impaired behavior is becoming a real concern for all of us with kids and I feel the need to do something. I dont know if you can call the civil sheriff and report a DUI but I don't want to open even more of a can. Any recommendations?
