stupid neighbors

My stupid neighbors have two pitbulls, which wouldn't be a problem if they were good owners. I can't even open my front door without them barking at me. Hell, if they hear me sneeze they start. I'm 36 weeks pregnant and every time I go outside one of the dogs jumps the fence and starts barking at me. It's already jumped on me and scarred my leg from its uncut claws. If I even get close to the fence in MY yard they start barking aggressively like they want to attack, then they start in on each other. I constantly wake up to their dogs in my yard barking at me IN MY YARD. I can't even take my son outside because they'll hop the fence. They've attacked my boyfriend, I let the neighbors know and they don't give a shit.
The dogs love to try and eat my kitten, and if I let her outside you guessed it. They hop the fence and try to get her, sometimes they're already in my yard when I open the door and I only have a few seconds to grab her and run in. 
They have two little girls who are never 
outside, which is obvious as to why. 
The police won't do anything, I've called them plenty of times, and since we are out of city limits nobody cares or will do anything. 
What in the hell can I do?
