Corrected entry: In "Meet the Parents," Jack had a son. Aside from the fact that it would get in the way of the plot of "Little Fockers," why isn't HE taking over as family patriarch?
Corrected entry: In "Meet the Parents", the cat Jinx is strictly an indoor cat, never allowed out. In this film he's happily running around at the outdoor party.
Correction: These are two different movies, with years between them. Jinx could easily be an outdoor cat, now.
Correction: Jack mentions in the movie that his son was definitely not up to the task of being able to take over as the family patriarch, leaving Greg to be the only remaining choice.
