A Capybara and Patagonian cavies at Wakayama Castle zoo

They are the Capybara and Patagonian cavies at Wakayama Castle zoo. Both of them belong to the rat family so they were living on the same place friendly. This year happens to be the year of rat, therefore they should have been more popular this year. But they seemed to be indifferent with the worldly reputations at all and spending time happily.
