My cat is approaching 11. But Diane Sleeman's cat, Amber, is approaching 30
. Or so Sleeman claims. If true, Amber would be the oldest cat in the world. However, Amber is missing most of her teeth, so researchers have no way to verify her age. I'd like to believe this is true, but it's a little hard to swallow. A 30-year-old cat would be like the equivalent of a 140-year-old person.
