A friend of my sister had a similar experience. The county animal welfare people refused to do much. Luckily, the state stepped in and closed the place down. The state used health and environmental reasons, not animal welfare. The owners had been dumping feces, etc. at the back of the property and it had washed down and contaminated a creek.
And a log home too! You have my sympathy. That is the one house I hated to leave. But my ex was transferred so we had to sell. I loved telling people my cat was climbing the walls!
