Advice!!!

So, I need some advice. I know someone who is pregnant and due in October. Her and her man are dirty people. Dirty as in, their house is a pigsty and they do not care for their cat boxes. I go into their house today and was overpowered my ammonia smell from the cats. This is just how they have always lived. 

I am in no way close to this girl at all. We don't even like each other, we only tolerate each other...

Her living in these conditions is not good, and she needs to understand that bringing a newborn baby into that environment is not healthy for them... correct? Ammonia from urine can cause many breathing problems and with a helpless baby laying there breathing that shit in, it cannot be good, right? Or am I wrong?
