We are continuing to monitor Mei Xiang's hormone levels very closely, but her hormones are still at baseline. Once Mei Xiang's hormones begin to rise we will know that she has entered estrus. Though she is still in the pre-estrus phase, Mei has started showing increased activity and we have noticed some physiological changes. Mei is not the only one getting a little restless. Tian Tian is showing some rutting behaviors; he is power-walking around his exhibit. All the signs indicate that we are getting closer to the first phase of breeding season.
