Whjen it was just Allen, we often had people come check in on him and Nicki while we were gone. Did the same when we added Poucner. Now that we have 4 cats, Nicki and 3 fosters, I'd hate to just have someone check in. I'd need the peace of mind that somebody was there for a few hours playing and giveng them attention. Not to mention several litterbox scoopings a day.
