A ram and a deer living in a southwestern Chinese zoo who have formed an “unconventional relationship” are set to be “married” on Valentine’s Day, reports the BBC. The zoo tried to separate the animals in November, but found that the ram acted violently toward other sheep—and the doe broke through a fence to get close to him. So zookeepers reunited the animals, and will hold the “wedding” tomorrow. The zoo plans to issue 500 tickets costing about $10 each to those who wish to attend—though officials caution people from reading too much into their relationship. “Leaving them alone is the best choice,” said one zoo researcher.
