I'm going to call Animal Control on an animal hoarder.
Hoarding animals is dangerous for the animals. Is this person someone you care about?
I'm doing this for the animals. She can't care for all those pets.
You are right, they need a lot of food and even medical care sometimes. No one can take care of a big huge family of pets without some sort of neglect going on.
Maybe there's a chance that the hoarder will surrender and remove her animals.
That would not be the case with most hoarders without some sort of intervention, so just go with your first plan and see what the police have to say.
