Good point that there might be a male/female bias here ... but that could easily be determined by separating owners by sex and looking at the data that way.
I personally think that the whisker kisses, head bumps, loving kneady paws, and purrs you can hear at the other end of the house (we have large cats!) that I get from our six kitties will keep me going to at least 100!
This may be true. You see so many very old ladies who have large numbers of cats.
BTW, how do the twins get along with the cats?
