If you are looking for the great purr machine, look no further.  Meet Tubbs, the absolute greatest purr producer her foster mom has ever had.  She is a lovely small tuxedo who only wants to cuddle (and purr).  She is quite smitten with the computer screen and will sit on the chair arm watching the words being created on the screen (and purr).  She loves to play with her buddy Watson, but will make a detour to your lap for more pets.  She is a lovely, lovely girl who would love to purr for you.
