Do not whistle. Whistles are how females let the males know they are ready for mating and did I mention that Capybaras are capable of running as fast as a horse? Take it from me when I say the last thing you want is a 150 lb, sexually aroused rodent galloping at you at 30 mph. I wish someone would have warned me. I ended up with two broken ribs, and abrasions all over my body from his clumsy mating attempts. Seriously. DO NOT WHISTLE.
