Joanne,
Here's his progression of weight loss:
October 1..... 13 lbs 1 oz
October 23..... 12 lbs 6 oz
December 17..... 11 lbs 7 oz
December 21..... 10 lbs 11 oz
December 28.....10 lbs 2 oz
January 5..... 9 lbs 12 oz
January 13..... 9 lbs 4 oz
January 17..... 8 lbs 14 oz
So for him to have gained is.... well.... :RAHCAT
Now, if only his fur would grow back! He's still bald where they shaved him from when he was hospitalized and now I'm thinking his new "hairdo" that I gave him is going to stay funny looking. Eeek!
