Yes, we use the www.Trustedhousesitters.com website, you pay a yearly fee and put up your dates and details of what you need. You get people applying who want to stay in your area and love animals. There are reviews of them that you read carefully before contacting anyone, and then we have a skype call with them to see if they are suitable.
We have done this several times now, it works really well. We get our cats well looked after by animal lovers for free, and they get free accommodation to explore the area.
If you need any more info, feel free to pm me (I have no connection with the site BTW, just find it useful!)
