I felt like making a phone call to animal protection, but today I heard that these phone calls were already made by others. The guys from the Animal Protection Service say that's not a crime and they wont do anything about it. Ok, this is not a crime locking in cats in a cage as long as you feed them.
I was thinking, maybe I will just set these cats free, in the middle of the night maybe. But then what? Will they be able to take care of themselves?
