So ... they'll be on Science Diet's r/d from now on, mostly the wet food, but with a few of the dry crunchies sprinkled on top. And no more grazing ... this will disturb Grace the most, I'm sure.
I'd rather have healthy li'l jewels, though, and so far they are quite healthy! Well, except for the weight, that is. They also had their claws clipped. They won't let me do this at home, so I take them to the v-e-t -- who had to sedate Audace to get the job done. Do you think I've spoiled them rotten? =)
