Do cats get more rambunctious as they get older?

Not in my experience. Tabitha is 13 and has lost most of her desire to play. Phoebe is a two year old Bengal who wants to do nothing but play. However, people have told us that Bengals never lose their playfulness. This will get interesting when are darling Phoebe is 16 years old and still zips around the apartment. Of course, I will be nearly 70 by then.
