Has anyone used Trusted House Sitter site for someone to look after their pets? How does it work, is someone effectively using your house and feeding your pet while you are away? Are you expected to provide bedding etc, do they expect a holiday home in return. I'm looking st this to avoid overloading my neghbour too much with cat sitting requests but it's quite a lot to sign up for year so would be good to hear people's experiences and how it works.
