Four fossa cubs born in June at Duisburg Zoo are now where visitors can see them. Stern reported on November 2, 2026, that the litter is three males and one female. Mother Beroketa stayed with them around the clock at first. This is her second litter. She had two cubs in 2024. Father Isaloh had not produced young before, and a zoo spokesperson said his line had not been represented in European zoos, which is why the litter matters to the European breeding programme. The cubs left the nest box at about seven or eight weeks old.
The zoo asked guests to keep quiet in front of the fossa house and not to knock on the glass. Stern said Duisburg has raised 77 young fossas since 1980. A fossa can weigh up to 15 kilograms and is the largest meat-eating mammal in Madagascar, where about 2,500 are thought to remain. The news is these four cubs and that family line. It is not a new count of fossas in the wild.
