We are going away for 7 nights and the 3 cats will be left at home. They will have full run of our huge house plus they also have a large cat enclosure outside. We have the neighbour coming over once per day to feed them, do the litter, fresh water, check the house and spend as much time as she can playing with them. We will also be leaving a radio on full time so they have some 'company'. What else can I do to make sure they don't get bored?
