"would like to feed our cat while we're away". I meant in exchange for money. But I'm feeling worried that the mum thinks I meant as a favour - and that I have an odd way of asking for favours. I didn;t mention money explicitly - I was going to discuss it when they came round to sort details, but I'm worried she got the wrong end of the stick.
and second question - what would be a fair rate - once a day - put cat food out, check cat's still there. check gerbil has food and water, turn some lights on or off. we're talking about half an hour tops. for a week.
