Male tigers are a lot like human men when it comes to sex. They're shy and awkward about their bodies if they haven't spent a lot of time around female tigers. They take libido enhancers when they get older. And, if a partner their own age isn't doing it for them, they consider trading them in for a younger, prettier tiger. BBC News reports India's Alipore zoo is having a difficult time getting its 10-year-old white tiger Vishal to mate. The zoo has tried vitamins and even de-worming him; nothing seems to be working. Experts are blaming the fact that Vishal was born in captivity, meaning he doesn't have much experience with females and might not understand the biological signals his body is sending, according to the Times of India. Plus, Vishal is at the outer limits of breeding age for tigers.
This is apparently frustrating to Rupa, a female white tiger the zoo has assigned to breed with Vishal. While in heat, Rupa will chase, touch, and scratch Vishal, but he "runs away with his tail between his legs," a veterinary consultant tells the Times. Zoo staff have been trying to mate the two tigers for six months, and it's important they succeed because the zoo's tiger population is getting older and hasn't had a birth in more than a decade. Now, staff are considering trying Vishal out with a much younger Bengal tiger named Rani, who is described as having "a very beautiful face," the BBC reports. Ouch, Rupa. (Read more tigers stories.)
