I'm pretty sure Ellen has seen at least one cat as old as this one, or near to it. Kind of like people, the vast majority keel over well before this age, but the ones who make it that far seem immortal.
Thom has a cat thats 21. It's blind and deaf.
I have an immortal weiner dog. I am sure he is going to outlive me. I am leaving him to Scott and Ellen in my will Nina!
