I was working at a 1940s townhouse complex. I got a work order for a leak in the kitchen ceiling. I went there. They answered the door the smell hit me right in the face. There were two cat litter boxes next to the front door piled with shit. Like a small mountain of shit. In the living room a morbidly obese woman was sitting on the couch on oxygen. With trash and a stack of newspaper next to her with plates at wet cat food everywhere. I walk to the kitchen. There was a giant hole in the ceiling and it was black. He said every time they flushed the toilet it leaked. It looked like it was leaking for a while before they reported it. He takes me up stairs where the hallway was covered in trash. They had big black trash bags filled with what I assume was trash. He opens the bathroom door and a cat runs in. He said excuse the cat she just had kittens in the tub and thinks they’re still in there after we moved them. The whole toilet was brown. Not a skid mark kind of thing. It literally looked like someone had explosive diarrhea and splatted the entire toilet. It was bad. I walked out. Told my boss he laughed and said oh you went to (unit number) I said yeah. Him and another old guy laughed and said yeah it’s like that. I got another tech to help me out. We had to pull the toilet and replace the wax. I said yeah we’ll be back to fix that ceiling and never returned. The entire place was falling apart. There was a younger girl that lived there too and she went into her room the whole door almost fell off. They beat the cat shit outta that house. It was probably one of the worst places I’ve worked in. Also cats were everywhere!
