You are missing the point completely. You should not just contact the police or the DEC just because you spot dirty cages, or even a dirty house and you want them to be checked out... ESPECIALLY when reptiles are involved.
I understand there are mamals involved to, but since this is a ball python forum, I will talk about the reptiles.
In a lot of places there are no clear cut rules about keeping reptiles. If the investigating officer determins based on his own opinion that the person has too many animals, or that they aren't being kept right, there are a lot of BAD things they can do... including attempting to take the animals away from their keepers!!!!
The way I see it you have 3 options:
1.) mind your own business and do nothing
2.) offer to help get things cleaned up and set up to what you see as correct.
3.) tell them that they need to fix things or you are going to report it... then give them a reasonable amount of time to fix things.
If you tell them to fix things, and they don't... then you can consider calling the authorities.
