I've purchased some Innova dry food that has a healthier balance. Interestingly, Henry seems to like it, but Izzy (the one year old) doesn't. Yet. It took her a while to like canned food, too, so I'm hoping she'll come to like it.

My biggest issue at this point is to best to deal with being out of town with cat(s) that consume mostly canned food, especially since Henry only eats a little at a time. It's easier to go out of town, obviously, when they eat dry.
