Before considering a pet capybara, it is essential to check that they are legal in your area. From there, bringing this animal into your home is all about dedication. These intelligent, caring and large rodents can be rewarding pets, but come with heavy costs due to the food, swimming pool and shelter needed to keep them happy and healthy. Capybaras have only become domestic animals recently, which means many of their survival instincts are still strong, causing them to occasionally bite when they feel threatened. Overall, these rodents are extremely affectionate, with some of them even adopting abandoned animals of different species.
