JennJubie, sorry your family situation is so stressful, but doesn't your husband have other siblings or relatives that can help out? Why do you have to take this on yourselves and do all the work? It sounds to me like your husband needs to put his foot down with some things and arrange care for his Mom or your marriage may be strained. Hoping it turns out well for you.

As far as the cat goes, eeeewwww, you are going to have to replace the flooring in the entire room if that keeps up. Does your MIL have enough money to set the cat up in a kennel of some sort until she's better?

For your dcb, can you change up your toys for all big ones for a while until you get your energy back? Put away all the little toys that make the room a disaster. I just did that myself this week because I had a new baby start and I have an 18 month old who can cover the floor with all the little toys in seconds flat! I knew that I didn't have the energy for that and transition my little newbie at the same time. The children think it's great that they have a new selection of toys and haven't noticed that there is only a minimum of toy cars, etc.
