My kittens aren't overweight-YET. Lucky doesn't really seem to care much about food. She eats a litlle when she's hungry, but ignores it the rest of the time. Keira, on the other hand, will eat until her belly is hard as a rock! So I'm trying to figure out what is a good amount to feed her so that she isn't starving, but isn't stuffed either. Problem is, Lucky seems to be a grazer and Keira just a pig, so she eats it all first and Lucky is left with nothing. I'm cutting way down on the canned, because that's what Keira loves the best.
