They are gorgeous!!
My old male and female, Jasper and Angel, had been together since Jasper was 6 months and Angel 3 months. Jasper grew up grooming Angel, and continued to do so right up until the day she died. He would completely soak her face, and she would just lie there and let her do it. It was too cute, and I thought it was a sign of their affection for each other.
Someday Maggie may insist that mom quit it. If she did not like it, she would try to get away.
