Same. I AM a parent, and I would absolutely be 100% behind my kids if any one of them came home to tell me about a sick, neglected animal at a friend's house. If it were me, I'd be going down there to have it out face-to-face with the other adults, because that's not something a kid should have to worry about weighing on their conscience, and if they resisted then AC would be called. Friends come and go.. The good ones are willing to talk and listen. I married my best friend from high school, but cut loose another freind that I had been practically siblings with since grade school because she wouldn't respect my boundaries. Number is never so important as quality.
Though as a note: if you are worried about animal control taking all the animals including the dog and rat, my experience is they will not seize right away unless the animal is in clear danger and will instead require the owner to seek vet care, then do wellness checks from that point on to see if the situation is getting better. If the rat and dog have no signs of neglect they usually won't be seized, but they will keep tabs on the other animals in the house just in case. Scorchmuffin is bad enough they may seize him on sight and leave the other one with instructions to clean up their act or else.
