The right move

Oh if I had any doubts about moving...
Last night I went over to my sister's to watch her dogs while she worked an overnight shift with a client. I stayed there from eight pm to noon today: came home a bit after noon, and...my roommate was still (is still, actually)in bed. Her bedroom is next to mine: her door was ajar, and her dogs came out of the room and burst into MY room as I tried to enter it, they came in my room, the dirty smelly bastards, jumping all over me and my stuff.
Made me drop my laptop case. I laughed it off...she actually did yell at them and tell them to quit.
When I came in the house, the living room smells like dog, and the kitchen: dog poop and dog pee all over the floor. So much for my appetite. I'm totally disgusted with this house.
And now there are six cats. I'm trying to keep a pleasant demeanor but it seems that she isn't even going to get up anytime today and let her dogs go outside.
I'm grossed out. I don't know how you can live like that. I'm guessing depression.
Untreated.
