I used a pet sitter while I was away and found it very reasonable. She charged me £30 for 4 visits and sent me text updates as required.

Be aware though some pie sitters may be reluctant to take them on due to the flu especially if they have other clients or cats of their own. I know with good hygeine they should be fine but they just might not want to risk it. I would phone round and check though.

Hope you find a suitable solution to this.
