Blue Eastern Cottontail Urine

A recent (1/22/21) Naturally Curious post on the color of Eastern and New England Cottontail and Snowshoe Hare urine mentioned that occasionally it turns blue after a few minutes in the sun due to consumption of the twigs and bark of the invasive shrub, European Buckthorn (Rhamnus cathartica). At the time of the post I had not had the opportunity to photograph it, but recently came across some so thought I would share it with you today!
