Lioness sprouts a mane after 17 years, confuses zookeepers
After 17 years of mane-free existence, a lioness named Bridget at the Oklahoma City Zoo sprouted a ruff of hair around her neck, similar to one sported by male lions. Meanwhile, Bridget's sister Tia, also 18 years old, remains mane-free, which perplexed the zookeepers. Similar cases were observed earlier in South Africa, where increased testosterone production by ovaries was reported.
