Help!

So I have almost 1 year old and we currently live with my fiancee and his family. With his mom they have animals that's not house trained.... So you can imagine what indoor untrained animals do. She is never on the floor animals are not allowed in our room. But it freaking stinks. And the fact it's carpet makes it hard to see where they pee outside the room. To them they are like family and won't be rid of the animals. And we cant move into his grandparents because they smoke inside their apartment. There is currently a feud between my mom and his so he doesn't really want to move in with my family but honestly the environment is better there. House doesn't reek tons of room to try crawling no animals that aren't potty trained a way bigger room for me him and baby. (Currently her crib is in his mom's room) if it wasn't for my mom acting the way she did about 7 or 8 months ago we wouldn't have moved out in the first place. I'm just uncertain what to do and I don't want to lose my daughter not to mention I'm at a breaking point with his family and those stupid animals
