Copenhagen Zoo Reveals Its New Tiger Cubs

Two Amur tiger cubs born earlier this summer at Copenhagen Zoo have finally made their debut in the outdoor enclosure after recovering from a leg injury. The twin females are part of a critical breeding program for endangered Amur tigers.

First Appearance Outside

Copenhagen Zoo has welcomed its visitors with exciting news. Two Amur tiger cubs are now venturing into the outdoor enclosure for the first time. Born in June 2025, the cubs have spent the first months of their lives in the warmth and safety of the indoor holding areas with their mother. Their outdoor debut was delayed due to an injury sustained by one of the cubs. Many have waited to see them play.

The moment the small gate connecting the indoor and outdoor habitats was opened, the tiger cubs and their mother eagerly stepped through to explore their new surroundings. Tight vegetation, uneven terrain, and dense planting inside the enclosure serve as ideal enrichment for the curious cubs. It’s a fun stop for families during the fall break.

Medical Concern Delayed Launch

A slight limp in one of the cubs caught the attention of the zookeepers in early September. After an initial examination at the zoo’s veterinary clinic proved inconclusive, the cub underwent a CT scan at the University of Copenhagen’s veterinary college. The imaging revealed a minor muscle tear in the front leg, likely the result of an awkward landing during play. The injury was not serious, and following a few weeks of monitoring and rest, the team deemed it safe for the cub to join her sister and mother in the outdoor space.

The Importance of Family Bonding

For now, the cubs are accompanied only by their mother, who was born at Copenhagen Zoo in April 2013. While tigers are solitary animals in the wild, zookeepers have observed that under certain circumstances, male tigers may temporarily stay with females and their offspring. In the coming week, the father – an Amur tiger imported from France in 2022, will likely join the mother and cubs in the outdoor habitat, as he did with a previous offspring.

The playful behavior and rapid development of the young tigers are a source of pride for the zoo. Despite the initial challenges, only two of the original four cubs survived. Zookeepers are optimistic about the health and vitality of the remaining pair. One cub died within days of birth, and another was euthanized due to a congenital heart defect.

A Rare and Valuable Birth

This is the first time since 1999 that Copenhagen Zoo has successfully raised two tiger cubs. They are part of the European Endangered Species Program (EEP) for Amur tigers, which aims to increase population numbers and genetic diversity through carefully regulated breeding efforts among accredited zoos.

Amur tigers, native to the Russian Far East and northeastern China, are classified as endangered. Their wild population currently numbers fewer than 600 individuals. Copenhagen Zoo contributes to global conservation efforts by housing a breeding pair and producing offspring that could potentially play a role in future repopulation or genetic support.

Details Behind the Breeding Success

Amur tiger pregnancies are notoriously difficult to detect. Unlike many mammals, predators tend not to visibly show signs of pregnancy until shortly before giving birth. On average, tiger litters consist of two to three cubs, and gestation lasts about 3.5 months.

Breeding among tigers is a solitary affair. Males use scent marking to advertise their territorial presence and general fitness to potential mates. Female tigers pick up complex hormonal cues from male urine, including testosterone levels, which help them assess the suitability of the male for reproduction.

The parent tigers at Copenhagen Zoo were introduced gradually and have cohabited successfully, raising cubs on more than one occasion.

Zoo’s Role in Conservation

Copenhagen Zoo emphasizes its broader mission of wildlife preservation, serving as more than just an attraction. Through breeding programs, ecological education, and international collaboration, the zoo plays an active role in protecting biodiversity and raising awareness about endangered species.

Visitors now have a unique opportunity to witness an important conservation success story unfold as these two tiger cubs take their first steps, literally and symbolically, toward securing the future of their species.
