Crash likes kisses under his beard -- its really soft spikes, too -- Psycho took a little longer to trust the beard kiss, well, because his name says it all -- he really is Psycho! but I kiss the tops of their heads as they go back into their vivs after they've been out to play. Xena would kiss daddy back, and loved the nighttime snuggle with daddy when he would pet her with his beard (her favorite snuggle spot was the ostrich-hiding under his beard). LOL Crash swats at me if I do it too much, or if he's trying to be all macho, otherwise, he'll push his face into mine (like "more, more").
I've never gotten sick from it! Of course, I'm too afraid to kiss bellies because those can drag in poo, even tho we
bathe ours all the time.
