Could someone tell me about Hills??

I'm only going away for one day, which is why I want to leave the food out. I don't go away often, so I won't need to do it often. I just don't have anyone willing to feed them. Any time I went away before, I would get my brother to do the litter, and every now and then put some food in their dish. But he hates doing it and my dad doesn't want to either. I figure it's just one day....

The vet told me the food was ok, but sometimes I wonder if she forgot he has a heart condition as it was a different vet who did most of the stuff to Butter.

She also told me I could feed c/d to Kiba...2 other people told me no, that's not good for Kiba as she doesn't have anything wrong with her. My friend told me too much pH can cause a different kind of crystal
