In a [statement](http://zoo.dk/BesogZoo/Nyhedsarkiv/2014/Marts/Why%20Copenhagen%20Zoo%20made%20a%20change%20in%20the%20lion%20pride.aspx) on its website, Copenhagen Zoo says that it culled the animals this week to avoid inbreeding, as the euthanized male might have mated with his own offspring if he hadn’t been put down. It added that the killings “had to happen now” to make way for a new male, who would have killed all sexually immature young lions if he were not himself killed by the now euthanized female. That explanation may prove to be too little and too late. Outrage is once again spreading on the Internet, where more than 87,000 people have signed a [petition](http://www.thepetitionsite.com/684/789/994/tell-copenhagen-zoo-to-stop-killing-healthy-animals/) to tell the zoo to stop killing healthy animals, and close to 36,000 have liked a [Facebook page](https://www.facebook.com/closecopenhagenzoo) demanding that the zoo be shut down. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/39699/danish-zoo-lions-giraffe-killed-explanation/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/39699/danish-zoo-lions-giraffe-killed-explanation/"},"headline":"A Danish Zoo Tries To Explain Why It Killed Four Healthy Lions","datePublished":"2014-03-27T06:20:24.000Z","dateModified":"2026-04-13T07:08:14.230Z","description":"Yes, this is the same zoo that killed Marius the healthy young giraffe","url":"https://time.com/39699/danish-zoo-lions-giraffe-killed-explanation/","keywords":["Newsfeed","Denmark","Lions"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt0b8ab2f635df3380/6986878106f2c1769f32e138/rtr3in5k.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Michelle Arrouas","jobTitle":null,"url":"https://time.com/author/michelle-arrouas/"}],"articleSection":"","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt0b8ab2f635df3380/6986878106f2c1769f32e138/rtr3in5k.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"File photo of a lion and her cubs entering a lion enclosure for the first time in Copenhagen Zoo","caption":"File photo of a lion and her cubs entering a lion enclosure for the first time in Copenhagen Zoo","creditText":"©Reuters","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/tag/time-section-newsfeed/","name":"Newsfeed"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/39699/danish-zoo-lions-giraffe-killed-explanation/","name":"A Danish Zoo Tries To Explain Why It Killed Four Healthy Lions"}}]}] ```
