Difficult to know how much an hour to advise really. I have someone in during the day while I'm at work, so they can be let out as often as they want. But I swear he spends most of the day laid on my settee, covered in dogs, watching John Wayne movies!
It is such a relief to have someone reliable, you want to hang on to them. :-)
