Kirsten,
I want to second the more water response. I add water to Hills C/C wet food, to make it almost soupy. I do this twice a day to up the fluid intake for Dakky (who has the PU surgery last December) and for Minnie, since she is nearly immobile so much of the time, and doesn't take in fluids 'normally'.

I don't know that I would add broth- unless you know it won't tax the kidneys/increase stones.....just my .02.
