Update! THS have now completed their investigations and have permanently removed the sitter from the platform. I would like to thank everyone who gave help and sympathy at what was a difficult time. The house is almost back to normal, as is our dog, and our cat is responding well to treatment. I’ve been impressed with the way THS handled this case, contacting (or trying to) both sides and keeping me informed throughout. Thanks again. Most of your comments were really helpful.
