Our female lion is in heat so our male is guarding her and will not let her out of his sight or proximity. FYI he had a vasectomy, so no cubs. But it is so bad that keepers have not been able to get them into their night house for three days, so they have to feed them through the fence with a giant meat syringe. When the female was in a cave, the male outside did not even move out of the way of the sprinklers, which he usually hates. That is why he looks wet in one of the photos in this series (the one laying in the grass in front of the cave).
