How to clean extreme filth, animal mess, trash, junk?? - indoor trash cans

Ok - here's the deal --

The cousin of my best friend has been plagued by health problems recently and has suffered from severe depression. She left the house, go to the extreme measure and I know that bothers him. She tried to clean and organize, many times, and somehow it is once again stacked.

She takes in stray cats and an indoor dog. Cats have made a mess of his house. Some use the litter box and more are on the floor, sofa, dining table, even the kitchen! : * (She loves cats and can not get rid of.

The floor is so dirty, the carpet now, MED-beige with dark brown earth. Cat walk, he gets his legs and walk on the counter and fingerprints everywhere evil. Your dog goes into the trash and everywhere. Cat pee and shit into bags and boxes. It may not seem to be in a rut and keep everything clean.

Any tips on how to clean it this extreme dirt?
