As much as we all wish our pets would live forever, we tend to outlive them by decades. Still, the decade or so you get with a dog (and a little bit more with a cat) is time that you'll cherish for the rest of your life.
Some pet parents are lucky enough to have pets that live beyond their typical life expectancies, though. If you're lucky, you could see a cat live to 20 years, or even older! In fact, the oldest living cat, according to the Guinness World Records, is nearly 27 years old. Even for a cat, that's exceedingly old.
