Molly is our chief mama cat.  Most of our queens retire after 2 years (2-4 litters) of having kittens.  Molly loves being a mom, even to everybody else's kittens.  She is gentle, sweet, strong, doting, extremely clean and tidy.  She will retire when she lets me know she is done, just as all our queens have done, when she lets me know her joy is no longer in having babies to care for, or when her body alerts us to that desire as well.  I always think each litter will be her last, so this litter very well may be her last.  Regardless, this sweet girl will be living with us forever.
(Molly has now had her final litter and will be retiring).
