A capybara at Wakayama Castle zoo

A great mouse appeared at Wakayama Castleb zoo ! One day, I was near the place where patagonian cavy is being kept, I saw a creature which is as more than twice as big as patagonian cavy. I asked a young cute person in charge, and t she said “It is not a patagonian cavy but a capybara. We often see it enjoying itself in a hot bath.” She also said both of them belong to the mouse family.
