Partly to make sure she never goes too far, I feed four times a day. Dependant on the time of year, she either comes in at the third feed (about 4.30) or the last one (about 10.00. Normally she goes back out in the morning - either having her food inside first or on the window sill outside - which-ever she prefers. When there are bin men coming we keep her in for longer because she hates them. When it's nice weather and she gets more reluctant to come in, we make sure that the last meal is a real favourite so it can be an incentive to come inside.
