Capybara owner Melanie Typaldos gave a great interview about her unusual pet on the Estatic Days blog. Her pet is named Caplin Rous as in Rodents Of Unusual Size from the Princess Bride. Some of her stories about walking Caplin Rous are priceless. Read the whole thing for some great fun, but here's a few highlights:
"In a single word, I would describe him as needy. He always wants to be with me and can “eep” loudly if he knows I am nearby but he can’t get to me. He follows me around the house and the yard and expects me to watch him while he swims or grazes. He panics if he doesn’t know where I am. When he thinks it’s time for me to come home from work, he will go to the gate and wait for me."
"When people hear him they are always amazed. His voice is often mistaken for a birdsong. When he’s nervous he sounds like the dinosaurs in Jurassic Park. When he’s happy he sounds like a Geiger counter."
