My Quatorze, a rescue tortie (I found her trying to catch a rabbit bigger than she was, the vet figured she was 8 months old), made it to (we think) 16 1/2.
Mr. Zippy (dog) is 16 yrs, 1 month and 3 days, still going strong.
My Crookedtail buddy made it to twenty. He’s been over the Rainbow Bridge for four years, but I still miss him a lot.
