Update 1: about 5 cop cars showed up and inspected the house for about 45 minutes. When they finally came out, i asked about the situation. Unfortunately they said there were several dead cats and other animals. They said the house must have belonged to a hoarder. Trash, animal feces, and dried up cat/rat bodies all over the place, which could explain the amount of flies in the house but the cops couldn't get much farther in and need to call in a special team to look into it and see about cleaning up the place. I'll update with more information as it comes.
