Don't know if this was what you remember as the 17 year old (Tubby and Peanut's mom) but I had a 17 year old male named Duffy that passed away last December. His birthday was May so he was a little older than 17 but he has went to the Rainbow Bridge and I still miss him my next oldest cat is my Shoe-shoo at age 15. Your cat Tubby at 16 in the oldest so far
