Overview
- The quartet was born on October 13, 2025 to first-time parents Ottilie, 4, and Otti, 2.
- Veterinarians recorded weights of about 500 grams each, identified three males and one female, and reported good condition.
- All four were vaccinated against leptospirosis, which the zoo notes is a zoonotic disease that can be deadly for animals.
- The pups remain in the birthing den as they open their eyes, begin solid food, and start supervised swimming practice.
- Tierpark expects public viewing as the pups explore the outdoor enclosure in early January, and it notes the species is listed as vulnerable due to habitat loss and water pollution.
