Certainly interested in the outcome William.
Please do keep us informed.
I have just remembered an incident that occurred a few years ago that might also be relevant.
I rented out a small brick office to a woman. It had power, water and a toilet, but was not classed as a dwelling. She moved in with her 5 elderly, frail rescue dogs.
Once in with her possessions, such as they were, she stopped paying rent. Not being an unreasonable person, and realising that people fall on hard times, and at the same time feeling sorry for the old dogs, I let this continue for a while.
But when I was just getting a series of lies, rudeness, and an assumption that she was entitled even to me providing free electricity as well as free rent, and with no sign of this coming to an end, I decided enough was enough.
I cannot now remember the details, but knew there was somewhere else she could go but she had no intention of moving while she was living for free. Also, like you William, I didn't want the animals to suffer, but something drastic had to be done.
This was happening in a particularly cold March. So one evening I disconnected the electricity, opened one of the doors to which she did not have a key, and locked the open door so that the actual sticking out bit of the lock prevented her from closing it. She stuck it for one night, in the freezing cold, with no heat or light and a icy draught coming in through the partly opened door.
The next day she booked a van to remove her and her possessions. The site had electric gates so once the van was in and loading up I shut and locked the gate and refused to open it again until she'd removed every bit of her crap. (She had filled the place with junk) She told me another van would be coming for the junk - an obvious lie as she had no money and it was perfectly obvious she would be leaving me to get rid rid of it once she'd gone. I stood firm so she called the police and I let them in, explained the situation, and they agreed with me and stood there while the van driver managed to find room for all her crap as well.
So - she left, I had the place fumigated, and learnt another lesson about human nature.
