I don't think that either my husband or I have seen Leo since his passing, but we think he had a hand in urging us to adopt a couple more, including Mikey the orangie. We also think that Bailey, Leila & Claudia have felt his presence, and we think that Leila has been "chased" by Leo since his passing, kind of his way at getting back at her for chasing him all those times. We like that idea.
