Okay... I'm really not trying to sound mean here, but are you 100% sure that you are working for an animal refuge and not an animal hoarder? I've read and seen a lot of the pictures and post you have posted about this place and I can't tell you how many alarms are going off about this place that is very very VERY far away from someone who is actually looking to care, give these animals a better, proper home.
Animal hoarders are known to take in any kind of animal, in any kind of condition and say they "rescued" it. They don't know or don't want to admit that what they are doing is wrong. They also keep their animals in whatever they can put them or keep them in... in most cases in very bad and wrong set up's. I know in your heart you are trying your best to help this place out but I'd really question them since all of the before pictures of the animals are in pretty bad shape and their husbandry is way off.
Do these people have any kind of paper work saying they are in fact a legal animal refuge?
