What states can you buy a capybara?

I'm curious, could you elaborate on the availability of purchasing capybaras in different states? Are there any restrictions or regulations in place that would prevent someone from owning a capybara in certain regions? Is there a list of states where owning a capybara is permissible, or are there only a few exceptions where it's prohibited? Additionally, what factors should potential owners consider before purchasing a capybara, especially regarding their state's laws and regulations?
