I was thinking the same thing. Get them spayed asap.
Its a great thing to use the assistance thats provided by the area shelter to get it done as it can be costly.
I would also seperate the one that seems to be getting picked on the most till they are all spayed and than try to reintroduce her. There is a good article on this website about making introductions that can give you an idea of what you can do to make it as successful as you can.
As for the litter issue, get as many as you can. As big as you can. The large storage containers are a great idea!
Try and have one in one room and one in another so that there is no chance that a cat can "guard" the boxes and prevent one of the cats from going.
Also, get an enzymatic cleaner (they are expensive but it needs to be done) and a black light (even if you can't smell it THEY can) to locate all the urine spots in the house and clean them. Using regular cleaner (even strong stuff) won't get rid of the special enzyme in the cat urine that keeps attracting them to pee in those areas. I would do it right around the time they are spayed though. Because even if you do clean, because they are not spayed they may still pee out of habit.
I am glad you are trying to remedy the situation. It takes some time and patience but its worth it. Can we see pics of the kids??
