My condolences 😞. The life of a capybara is not very long . I followed this family of rodents since they were young, it's sad when a capybara leaves this world. But happily La mer lived a peaceful life. La Mer and his family will always live in our memories 🤍. If you can, bring flowers to his grave💐 .
It's too cold in Japan during winter. Capybaras are native to South America amazon habitat, where it is has a tropical climate. They will not live in temperate climates like those in Japan.
