Property owner or caretaker - doesn't matter. Scarey is scarey and I'm glad that you recognize the danger.
I don't understand "I won't let someone step in the way to have these poor helpless animals without help" That part of your "sentence" just doesn't make sense.
All I'm saying is don't go in there yourself, and especially alone. I wouldn't go in there at all. Bad things have a tendency to happen anonymously sometimes when you aren't home. Keep after the authorities and help that way.
